kernel: sctp: fix race between sctp_wait_for_connect and peeloff

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the sctpwaitforconnect function, where a socket lock is temporarily released and re-acquired. During this brief period, another process can move the SCTP association to a...

kernel: sctp: diag: reject stale associations in dump_one path

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP diagnostics. When performing a socket diagnostic sockdiag lookup, the system may attempt to access memory related to an SCTP association that has already been freed. This can lead to an out-of-bounds read from...

kernel: tipc: fix slab-use-after-free Read in tipc_aead_decrypt_done

A flaw was found in the Linux kernel. A remote attacker could exploit a use-after-free vulnerability in the Transparent Inter-Process Communication TIPC cryptographic decryption process. This flaw occurs when a network namespace, a mechanism for isolating network resources, is deallocated before ...

kernel: tipc: clear sock->sk on the failed-insert path in tipc_sk_create()

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication protocol. A local attacker could exploit this vulnerability by repeatedly creating and failing to insert new sockets, causing the tipcskcreate function to leave a dangling pointer to a freed socket object. This...

kernel: sctp: fix auth_hmacs array size in struct sctp_cookie

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An incorrect array size calculation for the authhmacs field within the sctpcookie structure could lead to a buffer overflow. During the initialization of an SCTP association, if four HMAC identifiers...

kernel: netfilter: nf_log: validate MAC header was set before dumping it

A flaw was found in the Linux kernel's netfilter logging component. This vulnerability occurs because the system does not properly check if a network packet's Media Access Control MAC header is valid before attempting to log it. A local attacker could send a specially crafted network packet,...

kernel: netfilter: nf_conntrack_sip: don't use simple_strtoul

A flaw was found in the Linux kernel's netfilter SIP Session Initiation Protocol connection tracking module. This vulnerability, caused by unsafe port parsing, allows a remote attacker to send specially crafted malformed packets. Such packets could lead to excessive resource consumption,...

kernel: net: pull headers in qdisc_pkt_len_segs_init()

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...

kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show()

A flaw was found in the Linux kernel's SCSI target subsystem. This vulnerability, a buffer overflow, occurs in the tgptgpmembersshow function when processing long iSCSI IQN names. An attacker could potentially exploit this by providing a specially crafted input, leading to the disclosure of...

kernel: security/keys: fix missed RCU read section on lookup

A flaw was found in the Linux kernel's keyring code. The assocarrayfind function, used for looking up keys, was called without holding the necessary Read-Copy-Update RCU read lock. This oversight allows for a memory corruption vulnerability, particularly affecting persistent key handling, as the...
