CVE-2026-64596

CVE-2026-64596 affects the Linux kernel’s libfs handling. The vulnerability stemmed from init_pseudo() not setting SB_I_NOEXEC and SB_I_NODEV by default, allowing path_noexec() to warn when anonymous-inode files were mmap’d from certain superblocks. The fix sets both flags by default for every ps...

CVE-2026-64593

The CVE-2026-64593 issue affects the Linux kernel Btrfs trim path. A race/drop in device state handling can lead to a NULL device->bdev when re-scanning a previously missing device, causing a NULL pointer dereference during discard trimming (btrfs_trim_fs -> btrfs_trim_free_extents_throttle...

CVE-2026-64591

The CVE-2026-64591 entry concerns the Linux kernel Intel IOMMU (vt-d) driver and the SVA binding/unbinding logic when PRI is not supported. The root cause is that a previous commit skipped IOPF enablement for SVA on non-PRI hardware during bind, but the unbind path was not similarly updated, caus...

CVE-2026-64589

CVE-2026-64589 affects the Linux kernel i2c core. The issue arises when adapter registration fails: the release callback can dereference a NULL pointer because the completion struct is not initialised, potentially leading to a crash. Prior to the offending commit this would have caused a minor me...

CVE-2026-64586

CVE-2026-64586 Linux kernel vulnerability in brcmfmac: removal of devices could race with outstanding bus_reset work. The fix adds a per-bus mutex (bus_reset_lock) and routes arming of the bus_reset through brcmf_bus_schedule_reset(), cancels via brcmf_bus_cancel_reset_work(), and drains the runn...

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: arc: emac: quiesce interrupts before requesting IRQ Normal RX/TX interrupts are enabled later, in arcemacopen, so probe should not see interrupt delivery in the usual case. However, hardware may still present stale...

CVE-2026-64587

The CVE-2026-64587 entry concerns the Linux kernel net: ethernet: arc: emac component. The root cause is a race where, if probe unwinds after devm_request_irq() has installed the handler, a stale or latched interrupt may reach arc_emac_intr() during teardown and race with net_device release. The ...
