Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

smb: client: require a full NFS mode SID before reading mode bits

parse_dacl() treats an ACE SID matching sid_unix_NFS_mode as an NFS mode SID and reads sid.sub_auth[2] to recover the mode bits.

That assumes the ACE carries three subauthorities, but compare_sids() only compares min(a, b) subauthorities. A malicious server can return an ACE with num_subauth = 2 and sub_auth[] = {88, 3}, which still matches sid_unix_NFS_mode and then drives the sub_auth[2] read four bytes past the end of the ACE.

Require num_subauth >= 3 before treating the ACE as an NFS mode SID. This keeps the fix local to the special-SID mode path without changing compare_sids() semantics for the rest of cifsacl.

Affected: Ubuntu:26.04:LTS: linux, Ubuntu:26.04:LTS: linux-aws, Ubuntu:26.04:LTS: linux-gcp, Ubuntu:26.04:LTS: linux-ibm, Ubuntu:26.04:LTS: linux-oracle, Ubuntu:26.04:LTS: linux-realtime

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. (CVE-2025-54505)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Cryptographic API; - Rados block device (RBD) driver; - Compressed RAM block device driver; - Character device driver; - TPM device driver; - Hardware crypto device drivers; - EDAC drivers; - GPU drivers; - Greybus drivers; - HID subsystem; - Microsoft Hyper-V drivers; - Hardware monitoring drivers; - I2C subsystem; - IIO subsystem; - InfiniBand drivers; - Input Device core drivers; - LED subsystem; - Multiple devices driver; - Media drivers; - IBM Advanced System Management driver; - MTD block device drivers; - Network drivers; - Microsoft Azure Network Adapter (MANA) driver; - NTB driver; - NVME drivers; - Device tree and open firmware driver; - PCI subsystem; - Remote Processor subsystem; - SCSI subsystem; - SPI subsystem; - Realtek RTL8723BS SDIO drivers; - SM750 framebuffer staging driver; - Thermal drivers; - USB Gadget drivers; - USB over IP driver; - VFIO drivers; - Framebuffer layer; - 9P distributed file system; - AFS file…
