{"id":"DEBIAN-CVE-2024-49953","details":"In the Linux kernel, the following vulnerability has been resolved:  net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice  The km.state is not checked in driver's delayed work. When xfrm_state_check_expire() is called, the state can be reset to XFRM_STATE_EXPIRED, even if it is XFRM_STATE_DEAD already. This happens when xfrm state is deleted, but not freed yet. As __xfrm_state_delete() is called again in xfrm timer, the following crash occurs.  To fix this issue, skip xfrm_state_check_expire() if km.state is not XFRM_STATE_VALID.   Oops: general protection fault, probably for non-canonical address 0xdead000000000108: 0000 [#1] SMP  CPU: 5 UID: 0 PID: 7448 Comm: kworker/u102:2 Not tainted 6.11.0-rc2+ #1  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014  Workqueue: mlx5e_ipsec: eth%d mlx5e_ipsec_handle_sw_limits [mlx5_core]  RIP: 0010:__xfrm_state_delete+0x3d/0x1b0  Code: 0f 84 8b 01 00 00 48 89 fd c6 87 c8 00 00 00 05 48 8d bb 40 10 00 00 e8 11 04 1a 00 48 8b 95 b8 00 00 00 48 8b 85 c0 00 00 00 \u003c48\u003e 89 42 08 48 89 10 48 8b 55 10 48 b8 00 01 00 00 00 00 ad de 48  RSP: 0018:ffff88885f945ec8 EFLAGS: 00010246  RAX: dead000000000122 RBX: ffffffff82afa940 RCX: 0000000000000036  RDX: dead000000000100 RSI: 0000000000000000 RDI: ffffffff82afb980  RBP: ffff888109a20340 R08: ffff88885f945ea0 R09: 0000000000000000  R10: 0000000000000000 R11: ffff88885f945ff8 R12: 0000000000000246  R13: ffff888109a20340 R14: ffff88885f95f420 R15: ffff88885f95f400  FS:  0000000000000000(0000) GS:ffff88885f940000(0000) knlGS:0000000000000000  CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033  CR2: 00007f2163102430 CR3: 00000001128d6001 CR4: 0000000000370eb0  DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000  DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400  Call Trace:   \u003cIRQ\u003e   ? die_addr+0x33/0x90   ? exc_general_protection+0x1a2/0x390   ? asm_exc_general_protection+0x22/0x30   ? __xfrm_state_delete+0x3d/0x1b0   ? __xfrm_state_delete+0x2f/0x1b0   xfrm_timer_handler+0x174/0x350   ? __xfrm_state_delete+0x1b0/0x1b0   __hrtimer_run_queues+0x121/0x270   hrtimer_run_softirq+0x88/0xd0   handle_softirqs+0xcc/0x270   do_softirq+0x3c/0x50   \u003c/IRQ\u003e   \u003cTASK\u003e   __local_bh_enable_ip+0x47/0x50   mlx5e_ipsec_handle_sw_limits+0x7d/0x90 [mlx5_core]   process_one_work+0x137/0x2d0   worker_thread+0x28d/0x3a0   ? rescuer_thread+0x480/0x480   kthread+0xb8/0xe0   ? kthread_park+0x80/0x80   ret_from_fork+0x2d/0x50   ? kthread_park+0x80/0x80   ret_from_fork_asm+0x11/0x20   \u003c/TASK\u003e","modified":"2026-09-15T09:03:12.455000035Z","published":"2024-10-21T18:15:16.673Z","upstream":["CVE-2024-49953"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-49953"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-49953.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-49953.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
