CVE-2026-72391

Summary: CVE-2026-72391 affects the Linux kernel’s SFP MDIO bus handling. The code path in net: phy: sfp: free mii_bus in sfp_i2c_mdiobus_destroy previously leaked the struct mii_bus. The creation path allocates the I2C MDIO bus with mdio_i2c_alloc() (plain non-devm allocation) and registers it, ...

CVE-2026-72390

The CVE-2026-72390 issue is in the Linux kernel net/sched sch_teql implementation. The teql master->slaves singly linked list was not protected against concurrent writes, allowing a slab-use-after-free via teql_master_xmit() while another CPU could hold a stale pointer to the list. The fix add...

CVE-2026-72389

The vulnerability CVE-2026-72389 affects the Linux kernel’s bridge STP implementation. The root cause is a missing IFF_UP check in br_topology_change_detection(), which could allow arming the topology change timer while a bridge is administratively down, potentially causing a use-after-free when ...

CVE-2026-72387

The vulnerability CVE-2026-72387 affects the Linux kernel's DRM panthor path. A potential invalid pointer dereference could occur in group_process_tiler_oom() when heaps is an ERR_PTR(); panthor_heap_pool_put() could dereference that pointer. The fix ensures the pointer is set to NULL in that cas...

CVE-2026-72388

The CVE-2026-72388 entry concerns the Linux kernel DRM/Panthor driver. Root cause: when acquiring the dma_fence lock, drivers can be reached from hardirq context, requiring the IRQ-safe variant and a guard-model switch. Affected component is drm/panthor in the kernel’s fence handling; fix involve...

CVE-2026-72385

CVE-2026-72385 concerns the Linux kernel tracing/fprobe component. The issue is a NULL pointer dereference in fprobe_fgraph_entry() caused by mis-synchronization between two walks that size and fill a shadow-stack reservation under rcu_read_lock(). If a fprobe on an already-live ip becomes visibl...

CVE-2026-72386

The CVE-2026-72386 affects the Linux kernel, in the DRM Panthor component. It describes a leak that occurs when a group is evicted before the tiler_oom_work is serviced; a group reference is tied to the pending tiler_oom_work and must be released if the cancel is effective. The fix ensures the gr...

CVE-2026-72384

CVE-2026-72384 affects the Linux kernel irqchip/ts4800 driver. The vulnerability stems from missing cleanup of a chained interrupt handler installed during probe via irq_set_chained_handler_and_data(); the remove path does not clear this handler, creating a dangling callback that may run after th...

CVE-2026-72383

In the Linux kernel SCTP subsystem, CVE-2026-72383 describes a race in sctp_free_addr_wq() where addr_wq_timer could be re-entered after addr_wq_lock is held, allowing a sctp_addr_wq_timeout_handler() to access freed memory (use-after-free). The vulnerability is mitigated by calling timer_shutdow...

CVE-2026-72382

CVE-2026-72382 affects the Linux kernel ksmbd component. The issue is an unsigned underflow in parse_dacl() when computing the ACE count for a security descriptor, caused by subtracting sizeof(struct smb_acl) from a 16-bit DACL size. This can allow a malformed security descriptor to bypass the AC...

CVE-2026-72381

The CVE covers a Linux kernel use-after-free in ksmbd: fp->owner.name (a per-open kstrdup buffer) can be read while freed during a race between two concurrent SMB2 durable reconnects (DH2C/DHnC) on the same persistent_id. The issue stems from a read in ksmbd_vfs_compare_durable_owner() against...

CVE-2026-72379

The CVE-2026-72379 issue is in the Linux kernel: vfs_tmpfile() did not verify the caller’s fsuid/fsGid mappings, allowing O_TMPFILE creation on idmapped mounts when mapping does not cover the caller. The fix adds a missing fsuidgid_has_mapping() check so that O_TMPFILE creation is blocked unless ...

CVE-2026-72378

The CVE-2026-72378 entry concerns the Linux kernel, specifically the afs_extract_vl_addrs() path. The underlying issue is that error codes were only set on the first iteration of a loop; the patch fixes this by ensuring the correct error code is assigned on every iteration. This affects the AFS c...

CVE-2026-72377

Summary of CVE-2026-72377 : In the Linux kernel, a defect in AFS handling caused symlinks and mountpoints to incorrectly inherit AS_RELEASE_ALWAYS due to afs_apply_status(), even though they use afs_dir_aops which have no release_folio callback. This mismatch allowed memory management code to mis...

CVE-2026-72376

CVE-2026-72376 refers to a Linux kernel issue in the AFS subsystem where the counter net->cells_outstanding was incremented before the failure check of idr_alloc_cyclic(), leaving the count incremented when an error occurs. The fix corrects the order of operations so the increment happens only...

CVE-2026-72375

CVE-2026-72375 affects the Linux kernel and relates to the AFS subsystem. The issue arises from insufficient reinitialisation of afs_vnode::lock_work (and related lock_work handling) during inode allocation, causing intermittent warnings from debugobjects (e.g., “activate not available” messages ...

CVE-2026-72374

The CVE affects the Linux kernel AFS client: a bug in callback message parsing caused -EAGAIN to be swallowed (instead of being propagated by afs_extract_data), potentially impacting availability. The fix corrects the callback service message parsers to pass through -EAGAIN. CVSS 3.1 base score 7...

CVE-2026-72373

The CVE-2026-72373 entry concerns the Linux kernel. It fixes a NULL pointer dereference in afs_break_some_callbacks() by adding a check for NULL from afs_lookup_volume_rcu(), addressing cases where the specified AFS volume is unknown. The vulnerability description across sources aligns on this ro...

CVE-2026-72372

CVE-2026-72372 affects the Linux kernel in the afs subsystem, fixing a race when modifying net->cells_dyn_ino. The patch adds exclusive locking via net->cells_lock and changes the removal of a cell from net->cells_dyn_ino to afs_destroy_cell_work() instead of afs_cell_destroy(), because ...
