kernel: ALSA: seq: close a re-opened queue timer in the destructor

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer component. An unprivileged local user with access to the sound device can exploit a timing window during the cleanup of a queue timer. This allows the user to re-open a timer that has already been closed,...

kernel: drm/dp/mst: fix buffer overflows in sideband chunk accumulation

A flaw was found in the Linux kernel's DisplayPort DP Multi-Stream Transport MST subsystem. This vulnerability involves multiple buffer overflows within the drmdpsidebandappendpayload function when handling data from connected devices. A physically connected, malicious DP MST device can exploit...

kernel: ovl: check access to copy_file_range source with src mounter creds

A flaw was found in the Linux kernel's overlayfs component. When copying files across different overlay filesystems, the system incorrectly checked read permissions using the destination filesystem's credentials instead of the source's. This oversight could allow an unauthorized user to read file...

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: 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: perf: Fix addr_filter_ranges lifetime

A flaw was found in the Linux kernel's performance events perf subsystem. This vulnerability occurs because memory allocated for event address filters is released prematurely while still in active use by other kernel processes. A local user could exploit this use-after-free flaw during performanc...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 10.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

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...

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...
