In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: always free skb on ieee80211txprepareskb failure ieee80211txprepareskb has three error paths, but only two of them free the skb. The first error path ieee80211txprepare returning TXDROP does not free it, while...

CVE-2026-23429

A flaw was found in the Linux kernel. Specifically, within the input/output memory management unit IOMMU subsystem, a memory management error can occur. When the iommusvaunbinddevice function is called, it may attempt to access a memory area that has already been freed. This can lead to a system...

CVE-2026-23432

A flaw was found in the Linux kernel's mshv component. A local user could exploit a use-after-free vulnerability by unmapping memory after a specific error path in the mshvmapusermemory function. This can cause a system crash kernel panic due to the system attempting to access freed memory...

CVE-2026-23423

A flaw was found in the Linux kernel's btrfs file system. This vulnerability occurs in the btrfsuringreadextent function, where memory allocated for 'pages' is not properly freed when errors occur during read operations. This oversight can lead to resource exhaustion, potentially causing a Denial...

EUVD-2026-18643

In the Linux kernel, the following vulnerability has been resolved: btrfs: free pages on error in btrfsuringreadextent In this function the 'pages' object is never freed in the hopes that it is picked up by btrfsuringreadfinished whenever that executes in the future. But that's just the happy pat...

CVE-2026-23468

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Limit BO list entry count to prevent resource exhaustion Userspace can pass an arbitrary number of BO list entries via the bonumber field. Although the previous multiplication overflow check prevents out-of-bounds...

CVE-2026-23464

CVE-2026-23464 concerns the Linux kernel vulnerability in the Microchip PolarFire SoC mpfs driver. The issue is a memory leak in mpfs_sys_controller_probe(): if of_get_mtd_device_by_node() fails, the function returns early without freeing allocated memory for sys_controller. The fix routes error ...

CVE-2026-23432

CVE-2026-23432 : In the Linux kernel mshv component, there is a use-after-free in the error path of mshv_map_user_memory . The problem occurs when, in the error path, the code calls vfree() directly on a region while the MMU notifier remains registered; if userspace later unmaps that memory, the ...
