"description": "The Linux Kernel, the operating system core itself.\r\n\r\nSecurity Fix(es):\r\n\r\nA vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.(CVE-2024-1151)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nmlxsw: spectrum_acl_tcam: Fix NULL pointer dereference in error path\r\n\r\nWhen calling mlxsw_sp_acl_tcam_region_destroy() from an error path after\nfailing to attach the region to an ACL group, we hit a NULL pointer\ndereference upon 'region->group->tcam' [1].\r\n\r\nFix by retrieving the 'tcam' pointer using mlxsw_sp_acl_to_tcam().\r\n\r\n[1]\nBUG: kernel NULL pointer dereference, address: 0000000000000000\n[...]\nRIP: 0010:mlxsw_sp_acl_tcam_region_destroy+0xa0/0xd0\n[...]\nCall Trace:\n mlxsw_sp_acl_tcam_vchunk_get+0x88b/0xa20\n mlxsw_sp_acl_tcam_ventry_add+0x25/0xe0\n mlxsw_sp_acl_rule_add+0x47/0x240\n mlxsw_sp_flower_replace+0x1a9/0x1d0\n tc_setup_cb_add+0xdc/0x1c0\n fl_hw_replace_filter+0x146/0x1f0\n fl_change+0xc17/0x1360\n tc_new_tfilter+0x472/0xb90\n rtnetlink_rcv_msg+0x313/0x3b0\n netlink_rcv_skb+0x58/0x100\n netlink_unicast+0x244/0x390\n netlink_sendmsg+0x1e4/0x440\n ____sys_sendmsg+0x164/0x260\n ___sys_sendmsg+0x9a/0xe0\n __sys_sendmsg+0x7a/0xc0\n do_syscall_64+0x40/0xe0\n entry_SYSCALL_64_after_hwframe+0x63/0x6b(CVE-2024-26595)",
