kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...

kernel: ipv6: exthdrs: refresh nh after handling HAO option

A flaw was found in the Linux kernel's IPv6 extension header processing. When processing the Home Address Option HAO, the cached network header pointer may become invalid if the packet's memory is reallocated. This can lead to incorrect parsing of subsequent IPv6 Type-Length-Value TLV options,...

kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

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...
