CVE-2026-89539

Linux kernel SUNRPC subsystem: gssx_dec_option_array() processes wire-supplied GSS option entries and calls gssx_dec_linux_creds() for each CREDS_VALUE match. Because that helper unconditionally overwrites creds->cr_group_info without releasing the previous pointer, a reply containing two CRED...

CVE-2026-89524

This vulnerability affects the ath6kl WiFi driver in the Linux kernel . In ath6kl_cfg80211_connect_event(), fixed IE offsets (4 bytes for the association request, 6 bytes for the response) are subtracted from unsigned 8-bit length fields with no lower bound. When a malicious or malformed associat...

CVE-2026-89496

CVE-2026-89496 is a memory leak in the Linux kernel OCFS2 filesystem, discovered via local fuzzing of version 6.12.94 . The leak occurs when copy_file_range() is called within the same OCFS2 filesystem, triggering a copy-on-write path that fails to release deallocation caches (ocfs2_cache_block_d...

CVE-2026-89449

CVE-2026-89449 is a memory leak in the Linux kernel IOMMU subsystem, specifically in iommu_mock_device_add() (drivers/iommu/iommu.c). When iommu_fwspec_init() successfully allocates both dev->iommu and dev->iommu->fwspec, but the subsequent device_add() call fails, the error path only ca...

In the Linux kernel, the following vulnerability has been resolved: platform/x86: int1092: Fix potential memory leak in sarprobe The memory allocated for devicemodeinfo in parsepackage called by sargetdata is not freed in some of the error paths in sarprobe. Fix that by converting to use device...

CVE-2026-89437

CVE-2026-89437 affects the Linux kernel 's platform/x86 int1092 driver. The root cause is a memory leak in sar_probe() : memory allocated for device_mode_info by parse_package() (called via sar_get_data() ) is not freed along certain error paths. The fix converts these allocations to device-manag...

CVE-2026-81018

CVE-2026-81018 is a memory leak in the Linux kernel 's platform/x86: think-lmi driver. When multi-certificate support is active, the system authentication object stores ->signature and ->save_signature, which are not freed when the driver is removed. The fix frees these signatures on driver...
