https://notcve.org/view.php?id=CVE-2024-44970
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink When all the strides in a WQE have been consumed, the WQE is unlinked from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible to receive CQEs with 0 consumed strides for the same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the same wqe which corrupts the linked list. Fix this scenario by accepting 0 sized consumed strides without unlinking the WQE again. • https://git.kernel.org/stable/c/7b379353e9144e1f7460ff15f39862012c9d0d78 https://git.kernel.org/stable/c/650e24748e1e0a7ff91d5c72b72a2f2a452b5b76 https://git.kernel.org/stable/c/50d8009a0ac02c3311b23a0066511f8337bd88d9 https://git.kernel.org/stable/c/fba8334721e266f92079632598e46e5f89082f30 https://access.redhat.com/security/cve/CVE-2024-44970 https://bugzilla.redhat.com/show_bug.cgi?id=2309801 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-44969 – s390/sclp: Prevent release of buffer in I/O
https://notcve.org/view.php?id=CVE-2024-44969
In the Linux kernel, the following vulnerability has been resolved: s390/sclp: Prevent release of buffer in I/O When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time. Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction. • https://git.kernel.org/stable/c/7a7e60ed23d471a07dbbe72565d2992ee8244bbe https://git.kernel.org/stable/c/1ec5ea9e25f582fd6999393e2f2c3bf56f234e05 https://git.kernel.org/stable/c/a3e52a4c22c846858a6875e1c280030a3849e148 https://git.kernel.org/stable/c/a88a49473c94ccfd8dce1e766aacf3c627278463 https://git.kernel.org/stable/c/46f67233b011385d53cf14d272431755de3a7c79 https://git.kernel.org/stable/c/1e8b7fb427af6b2ddd54eff66a6b428a81c96633 https://git.kernel.org/stable/c/2429ea3b4330e3653b72b210a0d5f2a717359506 https://git.kernel.org/stable/c/bf365071ea92b9579d5a272679b74052a •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-44963 – btrfs: do not BUG_ON() when freeing tree block after error
https://notcve.org/view.php?id=CVE-2024-44963
In the Linux kernel, the following vulnerability has been resolved: btrfs: do not BUG_ON() when freeing tree block after error When freeing a tree block, at btrfs_free_tree_block(), if we fail to create a delayed reference we don't deal with the error and just do a BUG_ON(). The error most likely to happen is -ENOMEM, and we have a comment mentioning that only -ENOMEM can happen, but that is not true, because in case qgroups are enabled any error returned from btrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returned from btrfs_search_slot() for example) can be propagated back to btrfs_free_tree_block(). So stop doing a BUG_ON() and return the error to the callers and make them abort the transaction to prevent leaking space. Syzbot was triggering this, likely due to memory allocation failure injection. • https://git.kernel.org/stable/c/98251cd60b4d702a8a81de442ab621e83a3fb24f https://git.kernel.org/stable/c/bb3868033a4cccff7be57e9145f2117cbdc91c11 •

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Shutdown timer and prevent rearming when driver unloading When unload the btnxpuart driver, its associated timer will be deleted. If the timer happens to be modified at this moment, it leads to the kernel call this timer even after the driver unloaded, resulting in kernel panic. Use timer_shutdown_sync() instead of del_timer_sync() to prevent rearming. panic log: Internal error: Oops: 0000000086000007 [#1] PREEMPT SMP Modules linked in: algif_hash algif_skcipher af_alg moal(O) mlan(O) crct10dif_ce polyval_ce polyval_generic snd_soc_imx_card snd_soc_fsl_asoc_card snd_soc_imx_audmux mxc_jpeg_encdec v4l2_jpeg snd_soc_wm8962 snd_soc_fsl_micfil snd_soc_fsl_sai flexcan snd_soc_fsl_utils ap130x rpmsg_ctrl imx_pcm_dma can_dev rpmsg_char pwm_fan fuse [last unloaded: btnxpuart] CPU: 5 PID: 723 Comm: memtester Tainted: G O 6.6.23-lts-next-06207-g4aef2658ac28 #1 Hardware name: NXP i.MX95 19X19 board (DT) pstate: 20400009 (nzCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : 0xffff80007a2cf464 lr : call_timer_fn.isra.0+0x24/0x80 ...
