SUSE CVE-2026-31443

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix crash when the event log is disabled If reporting errors to the event log is not supported by the hardware, and an error that causes Function Level Reset FLR is received, the driver will try to restore the...

CVE-2026-31517

A flaw was found in the Linux kernel's IP-TFS IP-Transparent Fragmentation Service subsystem. A remote attacker could send specially crafted network packets that, during the reassembly process, cause the kernel to attempt an invalid operation on a network buffer. This improper handling of network...

CVE-2026-31515

A flaw was found in the Linux kernel. The pfkeysendmigrate function, which manages security associations, does not properly validate address families. This oversight can lead to an overfill of the socket buffer skb, a data structure used for network packets, when processing certain requests. A...

CVE-2026-31477

A flaw was found in ksmbd in the Linux kernel. Error handling issues within the smb2lock function can lead to memory leaks. Additionally, an allocation failure in smbflockinit can result in a NULL pointer dereference, causing the kernel to crash. This vulnerability could allow a local attacker to...

AZL-83375 CVE-2026-31450 affecting package kernel for versions less than 6.6.134.1-2

In the Linux kernel, the following vulnerability has been resolved: ext4: publish jinode after initialization ext4inodeattachjinode publishes ei-jinode to concurrent users. It used to set ei-jinode before jbd2journalinitjbdinode, allowing a reader to observe a non-NULL jinode with ivfsinode still...

CVE-2026-31456 mm/pagewalk: fix race between concurrent split and refault

In the Linux kernel, the following vulnerability has been resolved: mm/pagewalk: fix race between concurrent split and refault The splitting of a PUD entry in walkpudrange can race with a concurrent thread refaulting the PUD leaf entry causing it to try walking a PMD range that has disappeared. A...

CVE-2026-31450

CVE-2026-31450 describes a race in ext4 where ei->jinode was published to concurrent readers before jbd2_journal_init_jbd_inode() completed, allowing a non-NULL jinode to be observed with i_vfs_inode still NULL. The mitigated issue could lead to a crash when a reader passes jinode to jbd2_wait...
