In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix race condition in accept queue lifecycle In nfc llcp socket release, sockets and listener accept queues are walked under the local sockets rwlock and bh lock sock. However, bh lock sock does not synchronise against...

CVE-2026-98752: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: tty: port: fix ttyportttyvhangup race Drivers rely on ttyportttyvhangup to synchronously hang up their ports before tearing down resources as part of deregistration e.g. on physical disconnect. If ttyportttyvhangup races with...

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCB HAS METADATA leaves iocb-private as a uio meta, while iocb bio iopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdev direct IO, which never publishes...

In the Linux kernel, the following vulnerability has been resolved: tty: tty port: restore TTY IO ERROR on activation failure Make sure to restore the TTY IO ERROR flag if activation fails to prevent I/O attempts on a port that is gone or powered down. This specifically avoids issues like kernel...

CVE-2026-98616: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: reset numnapi when the napi vectors are freed fbn-numnapi is the count of live napi vectors, each of which owns an IRQ. The PM path had freed them without clearing the count. fbnicpmsuspend tears the datapath down via...

CVE-2026-98695: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: USB: serial: fix ioctl hangup race The tty ioctls can race with hangup and end up calling into a tty driver for a device that is already gone or powered down. Serialise the callbacks using the tty port mutex and add the missing...

CVE-2026-98651: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Properly handle NULL pointer in datcondsetstoragekey Some callers pass NULL as oldkey. Calling pagecondsetstoragekey will cause that NULL pointer to get dereferenced. Fix by checking for NULL and assigning the pointer ...

CVE-2026-98522: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Propagate map failures correctly from pvrmmumapsgl Map failure from pvrmmumapsgl interface was not returned correctly to pvrmmumap interface. This resulted in pvrmmumap interface to continue instead of returning ...

CVE-2026-98812: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/mctp: publish the mctpdev only after it is initialised mctpadddev links the new mctpdev into dev-mctpptr before mdev-dev is assigned, so a reader that picks the device up in that window dereferences a netdevice pointer that i...

CVE-2026-98785: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: check dcstatecreatecopy for NULL in dmsuspend dcstatecreatecopy can return NULL on allocation failure. dmsuspend only conditionally skips dmgpuresettoggleinterrupts and continues execution, returning success...

CVE-2026-98796: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: allocate dummy netdev sooner The RX rings and the shared NAPI are carried by an internal "dummy" netdev eth-dummydev. mtkprobe creates that dummy device, and adds the shared tx/rx NAPI to it, only after...

CVE-2026-98717: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Bail from shadow walks if the root is invalid or a dummy When walking shadow page tables, immediately terminate the walk if the root is a "dummy" root, i.e. a root whose top-level page table is backed by the zero...

CVE-2026-98676: Undefined Security Weakness

CVE-2026-98618: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Handle maximum standalone channels Standalone channels use one NAPI vector for each Tx and Rx queue. fbnic's allocation path excludes FBNICMAXTXQS from that layout. A 64-Tx/64-Rx configuration therefore records 128...
