CVE-2023-52767

CVE-2023-52767 : In the Linux kernel, a NULL dereference could occur in the TLS path when tls_sw_splice_eof() runs as part of sendfile() with an empty plaintext/ciphertext sk_msg. The issue caused tls_push_record() to take the split path and tls_merge_open_record(), which assumed at least one pop...

CVE-2023-52762

CVE-2023-52762 — Linux kernel virtio-blk overflow in max DMA size Root cause: In virtio-blk, an implicit conversion from size_t to u32 occurs when assigning (u32)max_size = (size_t)virtio_max_dma_size(vdev); If virtio_max_dma_size(vdev) returns a value larger than U32_MAX, the cast to u32 yields ...

CVE-2023-52755

CVE-2023-52755 affects the Linux kernel ksmbd path where a slab-out-of-bounds write could occur in smb_inherit_dacl() due to offsets exceeding the allocated size. The issue is fixed by adding checks to validate three offsets against the allocation size. Connected advisories (Astra Linux) repeat t...

CVE-2021-47432

CVE-2021-47432 relates to the Linux kernel. The vulnerability occurs in lib/generic-radix-tree.c: overflow in the peek() path when inode numbers are spread across the 64-bit inode space, triggering corner-case integer overflows in radix-tree usage. The connected Miracl e/MIRACLE_LINUX AXSA adviso...

CVE-2023-52746

CVE-2023-52746 concerns a Spectre v1 gadget in the Linux kernel’s xfrm_xlate32_attr() path. The vulnerability arises from using the user-provided nla_type as an array index when type > XFRMA_MAX, potentially leaking kernel memory. The patch set introduces array_index_nospec() use to prevent sp...

CVE-2023-52739

CVE-2023-52739 affects the Linux kernel; the issue is a race in the memory allocator where the PageHead check in __free_pages can be observed after the page reference is dropped, causing freeing of tail pages and potential page corruption or crashes. Root cause identified from the commit e320d301...

CVE-2023-52731

CVE-2023-52731 relates to the Linux kernel fbdev with deferred I/O. After a fbdev device is opened and closed, dirty pages can remain in the pageref list and may later be processed, risking memory/page corruption and an Oops. The fix adds cancellation of the delayed work and cleans up the pageref...

CVE-2023-52708

CVE-2023-52708 affects the Linux kernel MMC SPI code. The issue stems from error handling in mmc_spi_probe(): if mmc_add_host() fails, the code previously could call mmc_remove_host() and dereference a null device, causing a crash. The fix routes control to the fail_glue_init path on mmc_add_host...

CVE-2023-52705

CVE-2023-52705 is a kernel vulnerability affecting the nilfs2 filesystem code in Linux. The issue is an underflow/incorrect boundary calculation in NILFS_SB2_OFFSET_BYTES that computes the position of the second superblock, which can underflow when the device size is smaller than 4096 bytes. This...

CVE-2022-48708

The CVE-2022-48708 issue affects the Linux kernel’s pinctrl/pinmux subsystem. A NULL dereference could occur because pinmux_generic_get_function() could return NULL and the code dereferenced the function pointer without a NULL check, in pcs_set_mux(). The vulnerability was addressed by adding a N...
