CVE-2024-47749 – RDMA/cxgb4: Added NULL check for lookup_atid
https://notcve.org/view.php?id=CVE-2024-47749
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Added NULL check for lookup_atid The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the `act_establish()` and `act_open_rpl()` functions. Add a NULL check to prevent null pointer dereferencing. Found by Linux Verification Center (linuxtesting.org) with SVACE. In the Linux kernel, the following vulnerabili... • https://git.kernel.org/stable/c/cfdda9d764362ab77b11a410bb928400e6520d57 •
CVE-2024-47745 – mm: call the security_mmap_file() LSM hook in remap_file_pages()
https://notcve.org/view.php?id=CVE-2024-47745
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: mm: call the security_mmap_file() LSM hook in remap_file_pages() The remap_file_pages syscall handler calls do_mmap() directly, which doesn't contain the LSM security check. And if the process has called personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for RW pages, this will actually result in remapping the pages to RWX, bypassing a W^X policy enforced by SELinux. So we should check prot by security_mmap_file LSM hook... • https://git.kernel.org/stable/c/0f910dbf2f2a4a7820ba4bac7b280f7108aa05b1 •
CVE-2024-47742 – firmware_loader: Block path traversal
https://notcve.org/view.php?id=CVE-2024-47742
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: firmware_loader: Block path traversal Most firmware names are hardcoded strings, or are constructed from fairly constrained format strings where the dynamic parts are just some hex numbers or such. However, there are a couple codepaths in the kernel where firmware file names contain string components that are passed through from a device or semi-privileged userspace; the ones I could find (not counting interfaces that require root privilege... • https://git.kernel.org/stable/c/abb139e75c2cdbb955e840d6331cb5863e409d0e •
CVE-2024-47740 – f2fs: Require FMODE_WRITE for atomic write ioctls

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: f2fs: Require FMODE_WRITE for atomic write ioctls The F2FS ioctls for starting and committing atomic writes check for inode_owner_or_capable(), but this does not give LSMs like SELinux or Landlock an opportunity to deny the write access - if the caller's FSUID matches the inode's UID, inode_owner_or_capable() immediately returns true. There are scenarios where LSMs want to deny a process the ability to write particular files, even files tha... • https://git.kernel.org/stable/c/88b88a66797159949cec32eaab12b4968f6fae2d •
CVE-2024-47737 – nfsd: call cache_put if xdr_reserve_space returns NULL
https://notcve.org/view.php?id=CVE-2024-47737
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: nfsd: call cache_put if xdr_reserve_space returns NULL If not enough buffer space available, but idmap_lookup has triggered lookup_fn which calls cache_get and returns successfully. Then we missed to call cache_put here which pairs with cache_get. Reviwed-by: Jeff Layton

CVE-2024-47723 – jfs: fix out-of-bounds in dbNextAG() and diAlloc()

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: jfs: fix out-of-bounds in dbNextAG() and diAlloc() In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the cas... • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 •
