kernel: inet: frags: strip GSO state from fragments before reassembly

A flaw was found in the Linux kernel's network fragment reassembly process. An unprivileged local user, or a guest in a virtualized environment, could craft specially formed IPv4 or IPv6 network fragments that incorrectly retain Generic Segmentation Offload GSO state after reassembly. This...

kernel: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. The driver fails to validate the size of Video BIOS VBIOS tables, allowing the calculated entry count to exceed the bounds of an internal array. A local attacker or compromised firmware image could exploit this flaw to trigger an...

kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound

A flaw was found in the drm/vmwgfx component of the Linux kernel. An integer overflow vulnerability exists in the vmwshaderdefine function due to improper validation of user-supplied shader window size and offset. When the offset value is close to its maximum, an unsigned addition can wrap around...

kernel: perf: Fix use-after-free when perf mmap() revival races with the last munmap()

A flaw was found in the Linux kernel's perf subsystem. A race condition exists between the perf mmap revival and the last munmap operation. This allows a local unprivileged user to exploit a use-after-free vulnerability, leading to local privilege escalation to root...

kernel: ALSA: hda/cs35l41: Fix firmware load work teardown

A flaw was found in the Linux kernel's ALSA sound driver for the cs35l41 component. This vulnerability occurs because the driver fails to properly remove controls and cancel firmware load work during component unbinding or device removal, especially when firmware autostart is disabled. This can...

kernel: xfs: bounds-check buffer log item's dirty bitmap

A flaw was found in the Linux kernel's XFS filesystem. A local attacker, by mounting a specially crafted XFS image, could trigger an out-of-bounds write during log recovery. This vulnerability allows for kernel heap corruption, which could lead to a denial of service or potentially arbitrary code...

CVE-2020-1206-POC

CVE-2020-1206 Uninitialized Kernel Memory Read POC c 2020 ZecOps, Inc. - https://www.zecops.com - Find Attackers' Mistakes POC to check for CVE-2020-1206 / "SMBleed" Expected outcome: Local file containing target computer kernel memory. Intended only for educational and testing in corporate...

CVE-2026-98728

A flaw was found in the Linux kernel's Trusted Platform Module TPM driver. This flaw can lead to information disclosure when the kernel requests random data. Due to an incorrect bounds check when processing session-tagged responses, a truncated response can pass validation and cause the kernel to...

CVE-2026-98726

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express multipath subsystem. A malicious NVMe device can provide crafted Asymmetric Namespace Access ANA log data that triggers an integer underflow during buffer bounds validation. This failure leads to an out-of-bounds memory read,...

CVE-2026-98730

A flaw was found in the Linux kernel's Intel Bluetooth PCIe driver. A local user with access to the Bluetooth Host Controller Interface HCI user channel can inject an oversized transmission packet. Because the driver fails to validate packet length before copying data into a fixed-size memory...

CVE-2026-98727

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express multipath subsystem. The multipath driver inappropriately marks a storage device as supporting zoned storage before confirming its zone configuration. When a device reports a zone size of zero, subsequent read or write...

CVE-2026-98729

A flaw was found in the Linux kernel. On systems utilizing specific AMD processors, improper virtual address alignment for huge page memory mappings can allow a local user to cause a Denial of Service DoS. When unmapping these misaligned memory ranges during teardown, the kernel encounters an...

PT-2026-121879

In the Linux kernel, the following vulnerability has been resolved: net: cpsw new: unregister devlink on port registration failure cpsw probe registers devlink before registering the CPSW ports. If cpsw register ports fails, the error path only unregisters the notifiers and then releases the lowe...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.1.189, 6.6.158, 6.12.111, and 6.18.53. This vulnerability arises because the vb2videounregisterdevice function is not utilized when removing the video-i2c driver; as a result, the vb2 queue may fail to disconnect properly before...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.0. It stems from the fact that the isosockconnect function in Bluetooth ISO fails to serialize concurrent connect calls. As a result, multiple callers can pass through admission checks and replace socket connections simultaneously, leading...
