Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 4.17. It stems from the ASoC Samsung i2s driver, which in the probe function enables only the iis bus clock without activating the opclk as the parent clock for RCLKSRC mux. When the PM suspend callback runs, both clocks are disabled...

In the Linux kernel, the following vulnerability has been resolved: ptpqoriq: fix memory leak in probe Smatch complains that: drivers/ptp/ptpqoriq.c ptpqoriqprobe warn: ‘base’ from ioremap not released. Fix this by revising the parameter from ‘ptpqoriq-base’ to ‘base’. This is only a bug if...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: hid: cp2112: Fix duplicate workqueue initialization Previously, the cp2112 driver called INITDELAYEDWORK within cp2112 gpioirqstartup, resulting in duplicate initializations of the workqueue during subsequent IRQ starts after an...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: tty: serial: 8250: serialcs: Fixed a memory leak in the error handling path. In the probe function, if the serialconfig function fails, data from info is leaking. A resource handling path should be added to free up this memory...

CVE-2026-80953

In the Linux kernel, the following vulnerability has been resolved: i3c: master: adi: initialize the lock before enabling interrupts adii3cmasterprobe requests the IRQ and unmasks REGIRQPENDINGCMDR before the controller's IBI state, transfer queue list and transfer queue lock are initialized. A...

CVE-2026-89452

In the Linux kernel, the following vulnerability has been resolved: iommu/msm: Unwind probe state on registration failure msmiommuprobe adds its devm-managed IOMMU object to qcomiommudevices before adding the IOMMU sysfs device and registering it with the IOMMU core. If iommudevicesysfsadd fails,...

EUVD-2026-76290

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcxhr: initialize mutexes before requesting threaded IRQ pcxhrprobe requests pcxhrthreadedirq before initializing mgr-lock, even though the threaded handler takes that mutex. Initialize the manager locks before...

PT-2026-90070

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.2.6-1.1 Description A resource leak occurs in the rtw88 wifi driver during PCI initialization. The rtw pci probe function allocates PCI resources using rtw pci setup resource before initializing NAPI. If the rt...

PT-2026-90098

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The ALSA mts64 driver fails to validate if the devptr-id value is negative during the probe process. When bound via sysfs, a negative ID may be assigned, which can lead to Out-of-Bounds...

EUVD-2026-71247

In the Linux kernel, the following vulnerability has been resolved: ALSA: dummy: Check card index validity at probe snddummyprobe blindly trusts that the given devptr-id value is within the proper card index range. It's OK for the devices the driver itself creates at the module probe time, but if...

Linux Distros Unpatched Vulnerability : CVE-2026-80812

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ALSA: dummy: Check card index validity at probe snddummyprobe blindly trusts that the given devptr-id value is within the proper card index range. It's OK for t...

max77705_charger_probe() function within drivers/power/supply/max77705_charger.c Data Compromise

The vulnerability in the max77705chargerprobe function within the drivers/power/supply/max77705charger.c file of the Linux kernel power management driver is related to the reuse of previously freed memory. Exploitation of this vulnerability may allow an attacker to compromise the confidentiality,...

SUSE CVE-2026-72167

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: pl353: fix probe resource allocation During probe, the devmioremap is called with the parent device instead of the current one. So when the module is unloaded, the register area isn't released. Target the pl35x devi...

CVE-2026-80650 media: atomisp: gc2235: fix UAF and memory leak

In the Linux kernel, the following vulnerability has been resolved: media: atomisp: gc2235: fix UAF and memory leak gc2235probe handles its error paths incorrectly. If mediaentitypadsinit fails, gc2235remove is called, which tears down the subdev and frees dev, but then still falls through to...

PT-2026-82914

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference exists in the emac probe function. This occurs because devm request irq is called before devm platform ioremap resource, allowing an early interrupt to trigger...

CVE-2026-74734

A flaw was found in the Linux kernel's FireWire IEEE 1394 Open Host Controller Interface OHCI driver.
