CVE-2026-74293

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture System on Chip ASoC subsystem, specifically within the fslaudmix component. The fslaudmixputmixclksrc and fslaudmixputoutsrc functions do not properly validate user-provided enum values before processing them. This improper...

CVE-2026-74420

A flaw was found in the Linux kernel's GPU Shared Virtual Memory SVM subsystem. This vulnerability occurs when attempting to create an SVM range on Virtual Memory Areas VMAs that are not backed by physical page objects. An attacker could exploit this by triggering repeated page retrieval failures...

CVE-2026-74405

A flaw was found in the Linux kernel. A race condition exists within the Optimized Power Performance OPP subsystem, where a newly added OPP object is exposed before its internal reference count is fully initialized. A concurrent operation can then increment this uninitialized reference count,...

CVE-2026-74314

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This vulnerability arises from improper handling of special fields during the recycling of map values, which can lead to unsafe destruction operations. Specifically, in tracing programs operating within a Non-Maskable...

CVE-2026-74356

A flaw was found in the Linux kernel's vhost subsystem. An incorrect return value from the vhostgetavailidx function can cause the host to livelock. A malicious guest operating system OS can exploit this by not processing virtqueue entries, leading to the host repeatedly disabling notifications a...

CVE-2026-49426

When auditing a system call executed via ptracePTSCREMOTE, the kernel passed the return value of an internal setup function to AUDITSYSCALLEXIT rather than the actual result of the executed system call. As a result, committed audit records for system calls which returned an error do not reflect t...

CVE-2026-49419

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-72178

A flaw was found in the Linux kernel's DAMON Data Access MONitor subsystem. During an unsuccessful context commit operation, specifically in the damoncommittarget function, process identifiers PIDs may not be properly released. This resource leak can occur if the commit fails, for example, due to...

CVE-2026-72040

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. When a caller provides a message to the iipmirequest function, a reference count is incremented. However, if an error occurs during this process, the reference count is not properly decremented,...

CVE-2026-72004

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This issue occurs when the system attempts to copy Wi-Fi band structures, and an error during this process causes a memory resource to not be properly released. This oversight leads to a memory leak within the kernel, which could...

CVE-2026-72396

A flaw was found in the Linux kernel's hwmon subsystem, specifically in the adm1275 driver. This vulnerability allows a local attacker or a specially crafted device to trigger an out-of-bounds read during device name comparison. By providing a device name shorter than expected, uninitialized stac...

EUVD-2026-62231

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

CVE-2026-72283

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem. This vulnerability occurs when the system fails to update an Interrupt Remapping Table Entry IRTE for a bypass operation, which can leave a pointer to a memory location that has already been freed a 'dangling...

USN-8646-1: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - OCFS2 file system; - B.A.T.M.A.N. meshing protocol; - Netfilter; - SCTP protocol; CVE-2026-52914, CVE-2026-53002,...

CVE-2026-72397

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the pmbus/core module. The pmbusdata2regvid function incorrectly hardcoded the VR11 encoding, disregarding the vrmversion configured by the driver. This issue could lead to drivers sending dangerously wrong voltage codes ...

CVE-2026-72395

A flaw was found in the Linux kernel's hwmon pmbus subsystem. A worker designed to batch regulator events can combine multiple distinct hardware fault events into a single bitmask. This combined bitmask is then incorrectly processed by the critical hardware protection function,...

CVE-2026-72426

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The cleanfuncstate function, which manages stack slot cleanup, incorrectly clears metadata for pointer spills. This allows a subsequent read from a partially live stack slot to bypass crucial non-scalar register-fill...

CVE-2026-72137

A flaw was found in the xfrm subsystem of the Linux kernel, specifically within the natkeepalive component. This vulnerability occurs when the natkeepalivesend function attempts to free a network packet buffer skb that may have already been freed by the networking stack. This double free can lead...
