CVE-2026-45988 rxrpc: Fix re-decryption of RESPONSE packets

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix re-decryption of RESPONSE packets If a RESPONSE packet gets a temporary failure during processing, it may end up in a partially decrypted state - and then get requeued for a retry. Fix this by just discarding the packe...

CVE-2026-45986

The CVE-2026-45986 issue affects the Linux kernel crypto/ccree path, specifically a memory leak in cc_mac_digest. The root cause is a path where cc_map_hash_request_final() failures could leave memory unreleased; the fix adds cc_unmap_result() to prevent leaks. The vulnerability is locally exploi...

In the Linux kernel, the following vulnerability has been resolved: crypto: ccree - fix a memory leak in ccmacdigest Add ccunmapresult if ccmaphashrequestfinal fails to prevent potential memory leak...

CVE-2026-45836

A flaw was found in the Linux kernel's Bluetooth L2CAP subsystem. This vulnerability, a null-pointer dereference, occurs due to a missing NULL guard in the l2capsockgetsndtimeocb function. A local attacker could exploit this flaw to trigger a system crash, leading to a Denial of Service DoS...

CVE-2026-45834

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol implementation. A missing null pointer guard in the l2capsockstatechangecb function can lead to a null pointer dereference. This vulnerability could allow an attacker to cause a system crash,...

CVE-2026-45839

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter CO-RE Compile Once - Run Everywhere accessor parsing. A local attacker with CAPBPF capabilities could craft a malicious BPF program that uses negative CO-RE accessor indices. This input validation vulnerability allows for an...

CVE-2026-45837

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the arenavmclose function during a fork operation. This occurs because the child's Virtual Memory Area VMA is not correctly registered, leading to a dangling pointer. If a child process attempts to access this stale...

CVE-2026-45841

A flaw was found in the Linux kernel's netfilter component. A local attacker with CAPNETADMIN capabilities, which grants certain network administration privileges, could trigger a divide-by-zero error by adding a specially crafted fingerprint via nfnetlink. This vulnerability could lead to a kern...

CVE-2026-45840

A flaw was found in the Linux kernel's Open vSwitch component. A local attacker, with administrative network capabilities, could exploit this by providing an overly large Process ID PID array. This action triggers a buffer overflow within the network link netlink reply mechanism, leading to a...

CVE-2026-45842

A flaw was found in the Linux kernel's SLIP Serial Line Internet Protocol and PPP Point-to-Point Protocol components. An unprivileged local user can exploit this vulnerability by manipulating the PPPIOCSMAXCID ioctl to configure the SLIP Compressed Header SLHC state incorrectly. This...

CVE-2026-45844

A flaw was found in the Linux kernel's netfilter ARP Address Resolution Protocol tables. When processing IPv4-over-IEEE1394 ARP packets on IEEE1394 interfaces, the kernel incorrectly parses the ARP payload. This can lead to incorrect filtering decisions by arptables, where packets that should be...

CVE-2026-45843

A flaw was found in the Linux kernel's Serial Line Internet Protocol SLIP implementation. The slhcuncompress function, which handles VJ-compressed TCP headers, fails to perform proper bounds checks during packet processing. A remote attacker could exploit this by sending a specially crafted...

CVE-2025-71311

The CVE-2025-71311 vulnerability affects the Linux kernel’s ntfs3 code path. It arises when allocating new folios during ntfs_compress_write: if folios are not marked uptodate and ni_read_frame() is skipped because the caller expects a complete overwrite, some reserved folios may remain partially...

CVE-2026-45846

A flaw was found in the bareudp driver of the Linux kernel. This vulnerability allows a local attacker to trigger a NULL pointer dereference in the bareudpfillmetadatadst function. This occurs because the function attempts to access a NULL socket when the bareudp device is down, leading to a syst...

CVE-2026-45845

A flaw was found in the Linux kernel's TAPRIO Traffic Policing and Rate Limiting I/O qdisc. An unprivileged local user, with namespace-scoped CAPNETADMIN capabilities, can trigger a kernel null pointer dereference. This occurs by creating a TAPRIO qdisc in a new network namespace, grafting and th...

CVE-2026-45984

The CVE-2026-45984 issue is a concrete Linux-kernel vulnerability in the GFS2 iomap inline data write path. A data buffer head (dibh) is released prematurely via release_metapath() in gfs2_iomap_begin(), while iomap->inline_data still references dibh->b_data, causing a use-after-free when i...

CVE-2026-45983 nfsd: never defer requests during idmap lookup

In the Linux kernel, the following vulnerability has been resolved: nfsd: never defer requests during idmap lookup During v4 request compound arg decoding, some ops e.g. SETATTR can trigger idmap lookup upcalls. When those upcall responses get delayed beyond the allowed time limit, cachecheck wil...
