CVE-2026-31506

The CVE-2026-31506 issue concerns the Linux kernel bcmasp component where the Wake-on-LAN (WoL) IRQ handler could be double-freed. The problem stems from handling of the WoL irq; the patch indicates wol_irq does not need explicit freeing because it is allocated with devm_request_irq, and devres h...

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix double free of WoL irq We do not need to free wolirq since it was instantiated with devmrequestirq. So devres will free for us...

CVE-2026-31504

The CVE-2026-31504 entry describes a race in the Linux kernel’s networking stack: during a NETDEV_UP event, a socket re-registration into a fanout group’s arr[] can leave a dangling pointer if packet_release() doesn’t clear po->num while bind_lock is held. This Use-After-Free risk stems from a...

CVE-2026-31502

CVE-2026-31502 : The connected sources detail a Linux kernel vulnerability involving a type confusion in the team network device’s header_ops for non-Ethernet ports. The root cause is that team_setup_by_port() can copy port_dev->header_ops and later callbacks (dev_hard_header/dev_parse_header)...

CVE-2026-31489

This CVE (CVE-2026-31489) affects the Linux kernel meson-spicc SPI controller driver. The vulnerability arises from a double-put: meson_spicc_probe() registers the controller with devm_spi_register_controller(), and the removal path erroneously calls spi_controller_put() again in meson_spicc_remo...

CVE-2026-31489

In the Linux kernel, the following vulnerability has been resolved: spi: meson-spicc: Fix double-put in remove path mesonspiccprobe registers the controller with devmspiregistercontroller, so teardown already drops the controller reference via devm cleanup. Calling spicontrollerput again in...

CVE-2026-31486 hwmon: (pmbus/core) Protect regulator operations with mutex

In the Linux kernel, the following vulnerability has been resolved: hwmon: pmbus/core Protect regulator operations with mutex The regulator operations pmbusregulatorgetvoltage, pmbusregulatorsetvoltage, and pmbusregulatorlistvoltage access PMBus registers and shared data but were not protected by...

CVE-2026-31486

The CVE-2026-31486 entry concerns the Linux kernel hwmon/pmbus/core regulator operations (get_voltage, set_voltage, list_voltage) not being mutex-protected, risking race conditions when accessing PMBus registers and shared data. The fix reworks pmbus_regulator_notify() to perform notifications vi...

CVE-2026-31475

In CVE-2026-31475, the Linux kernel ASoC sma1307 component had a double-free issue: mode_set entries allocated with devm_kzalloc() were (incorrectly) freed with kfree() in an error path. The remedy documented across multiple sources is to drop the manual kfree() loop and rely on device resource m...

CVE-2026-31475 ASoC: sma1307: fix double free of devm_kzalloc() memory

In the Linux kernel, the following vulnerability has been resolved: ASoC: sma1307: fix double free of devmkzalloc memory A previous change added NULL checks and cleanup for allocation failures in sma1307settingloaded. However, the cleanup for modeset entries is wrong. Those entries are allocated...

CVE-2026-31440

CVE-2026-31440 affects the Linux kernel’s dmaengine idxd driver. The issue arises during device removal when a reset clears configuration registers, causing the prior check for event log support to fail if evl is no longer valid. The propagated fixes remove the check for “evl” enabled state and i...

CVE-2026-6862

CVE-2026-6862: A flaw in libefiboot (part of efivar) affects the device path node parser, which does not validate that each node’s Length is at least 4 bytes (EFI node header minimum). A crafted device path node could trigger infinite recursion, stack exhaustion, and a DoS via a process crash. Do...
