In the Linux kernel, the following vulnerability has been resolved: drm/xe: Free job before xe_exec_queue_put Free job depends on job->vm being valid, the last xe_exec_queue_put can destroy the VM. Prevent UAF by freeing job before xe_exec_queue_put.

In the Linux kernel, the following vulnerability has been resolved: ata: pata_macio: Fix DMA table overflow Kolbj rn and Jonáลก reported that their 32-bit PowerMacs were crashing in pata-macio since commit 09fe2bfa6b83 ("ata: pata_macio: Fix max_segment_size with PAGE_SIZE == 64K").

However with a sufficiently large request, the splitting logic causes each sg to be split into two commands in the DMA table, leading to overflow of the DMA table, triggering the BUG_ON(). With default settings the bug doesn't trigger, because the request size is limited by max_sectors_kb == 1280, however max_sectors_kb can be increased, and apparently some distros do that by default using udev rules. Fix the bug for 4KB kernels by reverting to the old max_segment_size. For 64KB kernels the sg_tablesize needs to be halved, to allow for the possibility that each sg will be split into two. • https://git.kernel.org/stable/c/09fe2bfa6b83f865126ce3964744863f69a4a030 https://git.kernel.org/stable/c/709e4c8f78e156ab332297bdd87527ec3da4e2d4 https://git.kernel.org/stable/c/822c8020aebcf5804a143b891e34f29873fee5e2 •

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-44974 – mptcp: pm: avoid possible UaF when selecting endp
https://notcve.org/view.php?id=CVE-2024-44974
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: avoid possible UaF when selecting endp select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free. A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with. • https://git.kernel.org/stable/c/01cacb00b35cb62b139f07d5f84bcf0eeda8eff6 https://git.kernel.org/stable/c/ddee5b4b6a1cc03c1e9921cf34382e094c2009f1 https://git.kernel.org/stable/c/f2c865e9e3ca44fc06b5f73b29a954775e4dbb38 https://git.kernel.org/stable/c/2b4f46f9503633dade75cb796dd1949d0e6581a1 https://git.kernel.org/stable/c/9a9afbbc3fbfca4975eea4aa5b18556db5a0c0b8 https://git.kernel.org/stable/c/0201d65d9806d287a00e0ba96f0321835631f63f https://git.kernel.org/stable/c/48e50dcbcbaaf713d82bf2da5c16aeced94ad07d •
