CVE-2026-53083

A flaw was found in the Linux kernel. A missing condresched in the bpffdarraymapclear loop, specifically when handling BPF Berkeley Packet Filter PROGARRAY maps with numerous entries, can lead to an RCU Read-Copy Update stall. This can result in a Denial of Service DoS under heavy system load, as...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dm: Clearing the clone request’s bio pointer when the last cloned bio is freed It was observed that stale values of rq-bio could lead to double initialization of cloned bios in request-based device-mapper targets, resulting in...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: rnbd-srv: Zero the rsp buffer before using it. Before using the data buffer to send back the response message, completely zero it. This prevents any stray bytes from being picked up by the client side when messages are exchanged...

kernel: exit: prevent preemption of oopsing TASK_DEAD task

A flaw was found in the Linux kernel. During the exit process of a task that has encountered an error, the system can incorrectly allow the task to be interrupted. This can lead to improper management of the task's memory, potentially causing memory corruption. Such an issue could allow a local...

kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel, as access to the global variable fgconsole is not properly synchronized, resulting in a use after free in confontop...

kernel: netfilter: xt_tcpmss: check remaining length before reading optlen

A flaw was found in the Linux kernel, specifically within the netfilter: xttcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

kernel: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

A flaw was found in the Linux kernel. A local attacker can exploit an out-of-bounds write vulnerability when the kernel recomputes an IPv6 Source Routing Header SRH. This issue occurs because insufficient headroom is reserved during the recompression process, leading to memory corruption...
