kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()
A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsitdecconnusagecount function, complete is called while still holding the conn-connusagelock spinlock. The waiting thread such as iscsitcloseconnection may wake up immediately and free the iscsitconn structure...
CVE-2026-53197
A flaw was found in the iptfs module of the Linux kernel. This issue, an ABBA deadlock, occurs when iptfsdestroystate attempts to cancel a timer while holding a spinlock that the timer's callback also tries to acquire. This circular dependency can cause the system to become unresponsive, leading ...

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: fix ABBA deadlock in iptfsdestroystate iptfsdestroystate calls hrtimercancel while holding a spinlock that the timer callback also acquires, leading to an ABBA deadlock on SMP systems. For the output timer iptfstimer...
CVE-2026-53197
CVE-2026-53197 affects the Linux kernel xfrm/iptfs path. The bug is an ABBA deadlock: iptfs_destroy_state() cancels an hrtimer while holding a spinlock that the timer callback also tries to acquire. The output timer (iptfs_timer) path holds x->lock before cancel, while the timer callback (iptf...
CVE-2026-53158
The CVE-2026-53158 issue affects the Linux kernel misc: fastrpc subsystem, where a NULL pointer dereference could occur in rpmsg callback if fastrpc_rpmsg_probe() hasn’t completed or if the callback fires before dev_set_drvdata(). The fault trace points to a NULL cctx in fastrpc_channel_ctx when ...

CVE-2026-52971 affects the Linux kernel ENA (Elastic Network Adapter) driver, specifically the PHC (Precision Time Protocol Hardware Clock) timestamp path get_timestamp. A race exists where phc->active is checked without holding the spinlock and resp is cached from ena_dev->phc.virt_addr be...
CVE-2026-52936
A flaw was found in the Linux kernel's jitterentropy cryptographic module. A long-held spinlock during entropy collection could cause parallel readers to stall. This issue allows a local attacker to trigger a Denial of Service DoS by causing contention for the shared lock, making the system...
