| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. |
| calibre is an e-book manager. Prior to 9.10.0, a malicious EPUB, OPF, or PDF file can execute arbitrary Python code when its metadata is read by calibre, including through Add books or Edit books, by embedding a custom column definition with a python: template in calibre:user_metadata that is passed unsanitized to exec() in the template formatter. This issue is fixed in version 9.10.0. |
| In the Linux kernel, the following vulnerability has been resolved:
selinux: check connect-related permissions on TCP Fast Open
Similar to Landlock, SELinux was not updated when TCP Fast Open
support was introduced to ensure connect-related permissions are
checked when using TCP Fast Open. Update its socket_sendmsg() hook to
call selinux_socket_connect() when MSG_FASTOPEN is passed. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: fix off-by-one in mapping pairs decoding bounds checks
In ntfs_mapping_pairs_decompress(), attr_end points one byte past the
end of the attribute record:
attr_end = (u8 *)attr + le32_to_cpu(attr->length);
The two bounds checks validating that mapping pair data bytes fit within
the attribute use strict greater-than (>), which allows a one-byte
out-of-bounds read when the data extends exactly to attr_end:
b = *buf & 0xf;
if (b) {
if (unlikely(buf + b > attr_end)) // off-by-one
goto io_error;
for (deltaxcn = (s8)buf[b--]; b; b--)
deltaxcn = (deltaxcn << 8) + buf[b];
}
When buf + b == attr_end, the check evaluates to false and buf[b] reads
one byte past the valid attribute boundary. The same pattern appears in
the LCN delta bytes check.
Fix both checks to use >= so that buf[b] at exactly attr_end is
correctly rejected as out of bounds. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: add bounds check before accessing EA entries
in ntfs_ea_lookup and ntfs_listxattr, this verifies that there is enough
space in the EA entry before accessing the next_entry_offset field of
the EA entry. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: not change 0-byte $DATA attribute to non-resident
When ntfs_resident_attr_resize() cannot grow a resident attribute in
place, it retries after converting other resident attributes to
non-resident to free space in the MFT recrord.
Do not select zero-length resident $DATA attributes for this conversion.
fsck treats 0-byte non-resident $DATA attribute as corruptions. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate index block header more strictly
Modify ntfs_index_block_inconsisent() to perform stricter validation of
INDEX_HEADER geometry in INDX blocks, and update
ntfs_lookup_inode_by_name() to use that function to validate INDX
blocks. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: free volume-wide resources on fill_super failure
ntfs_fill_super()'s err_out_now path frees only the volume struct via
kfree(vol), leaving several vol-owned allocations behind on every mount
failure:
- vol->nls_map, loaded by ntfs_init_fs_context() via
load_nls_default() (or replaced by an explicit nls= option in
ntfs_parse_param()), is never unload_nls()'d.
- vol->volume_label, allocated by load_system_files() through
ntfs_ucstonls() once the $Volume name attribute has been parsed, is
not released by load_system_files()'s own error labels nor by the
fill_super() inline cleanup that only runs on d_make_root()
failure. Any later failure inside load_system_files() leaks it.
- vol->lcn_empty_bits_per_page was kvfree()'d in
unl_upcase_iput_tmp_ino_err_out_now without clearing the pointer,
so it could not be folded into a single common cleanup.
Because the failure paths never call ntfs_volume_free() and never reach
the d_make_root() inline cleanup block (it sits above the label and is
jumped over by the load_system_files() / kvmalloc failure gotos), these
resources accumulate per failed mount attempt with no chance of
recovery short of unloading the module. This is a silent leak: the
inodes loaded prior to failure remain hashed but generic_shutdown_super()
skips evict_inodes() when sb->s_root is unset, so no CHECK_DATA_CORRUPTION
warning is emitted either.
Move the per-volume frees down to err_out_now and drop the
lcn_empty_bits_per_page kvfree() from the upper label so the cleanup is
performed exactly once on every failure path. Using unconditional
kvfree() / kfree() / unload_nls() is safe because they all accept NULL
and the upper labels that previously freed nls_map (the d_make_root()
inline cleanup) already clear the pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: centalize $INDEX_ROOT header validation
Add a dedicated helper to perform stricter validation of $INDEX_ROOT and
use it for both directory inodes and named index inodes. This keeps the
root size and header geometry checks consistent across both read paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: avoid heap allocation for free-cluster readahead state
get_nr_free_clusters() allocates a temporary file_ra_state before it
publishes the precomputed free cluster count, sets NVolFreeClusterKnown(),
and wakes vol->free_waitq. If that allocation fails, the worker returns
without setting the flag or waking waiters, so callers waiting for the free
count can block indefinitely.
The readahead state is only used synchronously while scanning the bitmap.
Keep it on the stack and pass it by address to the readahead helper. This
eliminates the early allocation failure path instead of adding a special
case that publishes a conservative count and wakes the waitqueue.
Zero-initialize the on-stack state because file_ra_state_init() only sets
ra_pages and prev_pos.
Apply the same treatment to __get_nr_free_mft_records(), which scans the
MFT bitmap with the same short-lived readahead state. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: validate index entries on reading
Validate index entries immediately after reading an index root or index
block from disk. This eliminates repeated checks in lookup and readdir,
and reduce the risk of missing checks in those paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: detect mapping-pairs LCN accumulator overflow
The NTFS mapping-pairs parser accumulates relative LCN deltas in a
signed integer. A corrupted attribute can drive that addition past
the representable range.
One corrupt runlist shape sets the accumulated LCN to S64_MAX and
then adds a delta of 1 in the next mapping-pairs entry.
Signed overflow is undefined and can turn an invalid runlist into a
different set of physical clusters.
Check the LCN addition for overflow before storing the next run. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: reject non-resident records for resident-only attributes
The shared lookup-time attribute validator rejects non-resident
$FILE_NAME and $VOLUME_NAME records because their formats require
resident values and callers handle returned records as resident
attributes. Other resident-only attribute types still pass through the
generic non-resident mapping-pairs checks.
That leaves real resident/non-resident union confusion paths. Inode load
looks up $STANDARD_INFORMATION and then reads data.resident.value_offset
without checking a->non_resident. ntfs_inode_sync_standard_information()
does the same when updating the standard information value.
ntfs_write_volume_flags() also looks up $VOLUME_INFORMATION and reads
data.resident.value_offset directly. $INDEX_ROOT callers in dir.c and
index.c depend on the same lookup contract before consuming the resident
index root value.
Reject non-resident records for all resident-only attribute types in the
shared validator. Keep the existing $FILE_NAME and $VOLUME_NAME behavior,
but factor it through a helper and extend it to
$STANDARD_INFORMATION, $OBJECT_ID, $VOLUME_INFORMATION, $INDEX_ROOT, and
$EA_INFORMATION. For $OBJECT_ID and $EA_INFORMATION this is contract
hardening for resident-only formats; this patch only rejects the
non-resident form and does not add new resident value validation for
those types. |

ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2_sum_rightmost_rec
[BUG]
On-disk corruption setting l_next_free_rec to 0 in an inode's embedded
extent list triggers a UBSAN panic on the next write to that file.
[CAUSE]
ocfs2_sum_rightmost_rec() computes
i = le16_to_cpu(el->l_next_free_rec) - 1
and accesses el->l_recs[i] without validating i. When l_next_free_rec
is 0, i becomes -1; when l_next_free_rec exceeds l_count, i falls
past the end of the array. Either case violates the
__counted_by_le(l_count) annotation on l_recs[] and triggers UBSAN.
[FIX]
Validate the inode's embedded extent list when the inode is read, in
ocfs2_validate_inode_block(): l_count must be non-zero and no larger
than the inode block can hold, and l_next_free_rec must not exceed
l_count. A corrupt list is rejected at read time, before the b-tree
code can index l_recs[] out of bounds. |

sunrpc: fix uninitialized xprt_create_args structure
The xprt_create_args structure is allocated on the stack without
initialization in rpc_sysfs_xprt_switch_add_xprt_store(). While some
fields are manually populated, critical fields like srcaddr, bc_xps,
and flags contain uninitialized stack garbage.
This can lead to:
1. Kernel panic when xs_setup_xprt() dereferences garbage srcaddr
2. Information leak if srcaddr points to sensitive stack data
3. Unpredictable behavior if flags has random bits set
The fix is to zero-initialize the structure to ensure all unused
fields are NULL/0, preventing the transport setup code from acting
on garbage data. |
| The Quill Forms | Conversational Multi Step Forms, Surveys & quizzes plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 5.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |

wifi: rt2x00: avoid full teardown before work setup in probe
rt2x00lib_probe_dev() uses the full rt2x00lib_remove_dev() teardown for
all probe failures. However, drv_data allocation and workqueue allocation
can fail before intf_work, autowakeup_work and sleep_work have been
initialized.
Do not enter the full remove path until the probe has reached the point
where those work items are set up. Return directly for drv_data allocation
failure, and use a small early cleanup path for workqueue allocation
failure.
This issue was found by our static analysis tool and then confirmed by
manual review of rt2x00lib_probe_dev() and rt2x00lib_remove_dev(). The
early probe exits should not call a common teardown path that assumes the
later work setup has already completed.
A QEMU PoC forced alloc_ordered_workqueue() to fail before the work
initializers are reached. The resulting fail path entered
rt2x00lib_remove_dev(), and DEBUG_OBJECTS reported invalid work drains with
rt2x00lib_probe_dev() and rt2x00lib_remove_dev() in the stack. |

cgroup/cpuset: rebind mm mempolicy to effective_mems, not mems_allowed
Creating a child cpuset where cpuset.mems is never set leads to a div/0
when a VMA mempolicy with MPOL_F_RELATIVE_NODES rebinds in response to a
CPU hotplug event.
Reproduction steps:
1) Create a cgroup w/ cpuset controls (do not set cpuset.mems)
2) Move the task into the child cpuset
3) Create a VMA mempolicy for that task with MPOL_F_RELATIVE_NODES
4) unplug and hotplug a cpu
echo 0 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu1/online
5) mempolicy rebind does a div/0 in mpol_relative_nodemask on the
call to __nodes_fold()
The cpuset code passes (cs->mems_allowed) which is not guaranteed to have
nodes to the rebind routine. Use cs->effective_mems instead, which is
guaranteed to have a non-empty nodemask once we reach that code path.

octeontx2-pf: fix SQB pointer leak on init failure
otx2_init_hw_resources() initializes SQ aura and pool resources before
several later setup steps. On failure, err_free_sq_ptrs only frees SQB
pages, leaving the per-SQ sqb_ptrs arrays behind.
Use otx2_free_sq_res() for the SQ unwind path and let it free sqb_ptrs
even when sq->sqe has not been allocated yet.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have an
OcteonTX2 PF device and the corresponding AF mailbox setup to test with,
no runtime testing was able to be performed. |
