kernel: net: atm: fix crash due to unvalidated vcc pointer in sigd_send()

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM networking component. A local attacker, by acting as a malicious signaling daemon, could send a specially crafted message containing an unvalidated pointer. This unvalidated pointer would be directly used by the kernel, leading...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

kernel: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath

A flaw was found in the Linux kernel's CIFS Common Internet File System client. When the cifssanitizeprepath function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-boun...

kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels

A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...
