CVE-2024-49932 – btrfs: don't readahead the relocation inode on RST
https://notcve.org/view.php?id=CVE-2024-49932
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: don't readahead the relocation inode on RST On relocation we're doing readahead on the relocation inode, but if the filesystem is backed by a RAID stripe tree we can get ENOENT (e.g. due to preallocated extents not being mapped in the RST) from the lookup. But readahead doesn't handle the error and submits invalid reads to the device, causing an assertion in the scatter-gather list code: BTRFS info (device nvme1n1): balance: st... • https://git.kernel.org/stable/c/f7a1218a983ab98aba140dc20b25f60b39ee4033 •
CVE-2024-49930 – wifi: ath11k: fix array out-of-bound access in SoC stats
https://notcve.org/view.php?id=CVE-2024-49930
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix array out-of-bound access in SoC stats Currently, the ath11k_soc_dp_stats::hal_reo_error array is defined with a maximum size of DP_REO_DST_RING_MAX. However, the ath11k_dp_process_rx() function access ath11k_soc_dp_stats::hal_reo_error using the REO destination SRNG ring ID, which is incorrect. SRNG ring ID differ from normal ring ID, and this usage leads to out-of-bounds array access. To fix this issue, modify ath11k_d... • https://git.kernel.org/stable/c/d5c65159f2895379e11ca13f62feabe93278985d •
CVE-2024-49929 – wifi: iwlwifi: mvm: avoid NULL pointer dereference
https://notcve.org/view.php?id=CVE-2024-49929
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: avoid NULL pointer dereference iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta pointer is not NULL. It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is dereferencing the ieee80211_sta pointer. If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL pointer. Fix this by checking the sta pointer before retrieving the mvmsta from it. If sta is not NULL, then mvmsta isn't either... • https://git.kernel.org/stable/c/cbc6fc9cfcde151ff5eadaefdc6155f99579384f •

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: fbdev: efifb: Register sysfs groups through driver core The driver core can register and cleanup sysfs groups already. Make use of that functionality to simplify the error handling and cleanup. Also avoid a UAF race during unregistering where the sysctl attributes were usable after the info struct was freed. • https://git.kernel.org/stable/c/2a9c40c72097b583b23aeb2a26d429ccfc81fbc1 •

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: fbdev: pxafb: Fix possible use after free in pxafb_task() In the pxafb_probe function, it calls the pxafb_init_fbinfo function, after which &fbi->task is associated with pxafb_task. Moreover, within this pxafb_init_fbinfo function, the pxafb_blank function within the &pxafb_ops struct is capable of scheduling work.
