| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Check for probe() id argument being NULL
The probe() id argument may be NULL in 2 scenarios:
1. brcmf_pcie_pm_leave_D3() calling brcmf_pcie_probe() to reprobe
the device.
2. If a user tries to manually bind the driver from sysfs then the sdio /
pcie / usb probe() function gets called with NULL as id argument.
1. Is being hit by users causing the following oops on resume and causing
wifi to stop working:
BUG: kernel NULL pointer dereference, address: 0000000000000018

<snip>
Fix this by checking for id being NULL.
In the PCI and USB cases try a manual lookup of the id so that manually
binding the driver through sysfs and more importantly brcmf_pcie_probe()
on resume will work.
For the SDIO case there is no helper to do a manual sdio_device_id lookup,
so just directly error out on a NULL id there. |

bpf, cpumap: Make sure kthread is running before map update returns
The following warning was reported when running stress-mode enabled
xdp_redirect_cpu with some RT threads:

The root cause is the same as commit 436901649731 ("bpf: cpumap: Fix memory
leak in cpu_map_update_elem"). The kthread is stopped prematurely by
kthread_stop() in cpu_map_kthread_stop(), and kthread() doesn't call
cpu_map_kthread_run() at all but XDP program has already queued some
frames or skbs into ptr_ring. So when __cpu_map_ring_cleanup() checks
the ptr_ring, it will find it was not emptied and report a warning.
An alternative fix is to use __cpu_map_ring_cleanup() to drop these
pending frames or skbs when kthread_stop() returns -EINTR, but it may
confuse the user, because these frames or skbs have been handled
correctly by XDP program. So instead of dropping these frames or skbs,
just make sure the per-cpu kthread is running before
__cpu_map_entry_alloc() returns.
After apply the fix, the error handle for kthread_stop() will be
unnecessary because it will always return 0, so just remove it. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()
nl80211_parse_mbssid_elems() uses a u8 variable num_elems to count the
number of MBSSID elements in the nested netlink attribute attrs, which can
lead to an integer overflow if a user of the nl80211 interface specifies
256 or more elements in the corresponding attribute in userspace. The
integer overflow can lead to a heap buffer overflow as num_elems determines
the size of the trailing array in elems, and this array is thereafter
written to for each element in attrs.
Note that this vulnerability only affects devices with the
wiphy->mbssid_max_interfaces member set for the wireless physical device
struct in the device driver, and can only be triggered by a process with
CAP_NET_ADMIN capabilities.
Fix this by checking for a maximum of 255 elements in attrs. |
| In the Linux kernel, the following vulnerability has been resolved:
bonding: do not assume skb mac_header is set
Drivers must not assume in their ndo_start_xmit() that
skbs have their mac_header set. skb->data is all what is needed.
bonding seems to be one of the last offender as caught by syzbot:

nfc/nci: Add the inconsistency check between the input data length and count
write$nci(r0, &(0x7f0000000740)=ANY=[@ANYBLOB="610501"], 0xf)
Syzbot constructed a write() call with a data length of 3 bytes but a count value
of 15, which passed too little data to meet the basic requirements of the function
nci_rf_intf_activated_ntf_packet().
Therefore, increasing the comparison between data length and count value to avoid
problems caused by inconsistent data length and count. |

Fix it by checking handle was looked up successfully or otherwise fail the
extension by jumping into the existing unwind.
