UBUNTU-CVE-2026-43295

In the Linux kernel, the following vulnerability has been resolved: rapidio: replace riofreenet with kfree in rioscanallocnet When idtab allocation fails, net is not registered with rioaddnet yet, so kfreenet is sufficient to release the memory. Set mport-net to NULL to avoid dangling pointer...

CVE-2026-43217

A flaw was found in the Linux kernel's media: iris: gen2 component. When a session is stopped, a memory deallocation occurs. If a subsequent streaming stop operation is initiated without proper validation, it attempts to access already freed memory. This can be triggered by a local attacker or a...

CVE-2026-43104

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix a memory leak in hang state error path When vc4savehangstate encounters an early return condition, it returns without freeing the previously allocated kernelstate, leaking memory. Add the missing kfree calls by...

CVE-2026-43091

The CVE-2026-43091 vulnerability affects the Linux kernel xfrm policy handling during netns exit. The root cause is that xfrm_policy_fini() frees the policy_bydst hash tables after flushing work items and deleting policies, but does not wait for concurrent RCU readers to exit read-side critical s...

kernel: scsi: qla2xxx: Fix improper freeing of purex item

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix improper freeing of purex item In qla2xxxprocesspurlsiocb, an item is allocated via qla27xxcopymultiplepkt, which internally calls qla24xxallocpurexitem. The qla24xxallocpurexitem function may return a...

PT-2026-34379

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the isotp sendmsg function. The function uses cmpxchg on so-tx.state to serialize access to so-tx.buf. When isotp release waits for ISOTP IDLE via wait...

kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix use-after-free in iscsitdecsessionusagecount In iscsitdecsessionusagecount, the function calls complete while holding the sess-sessionusagelock. Similar to the connection usage count logic, the waiter...

libtiff: libtiff: Denial of service via double free in tiffcrop.c

A denial of service flaw via segmentation fault has been found in libtiff. This segmentation fault vulnerability is caused by accessing invalid or corrupted memory addresses during memory deallocation operations. The root issue lies in the cleanup logic of the main function where the program...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the session restoration process. An attacker can execute arbitrary memory deallocation by injecting a crafted session into the cache and triggering the application to call the relevant session restor...
