The C reproducer is trying to run the following bpf prog: 0: (18) r0 = 0x0 2: (18) r1 = map[id:49] 4: (b7) r8 = 16777216 5: (7b) *(u64 *)(r10 -8) = r8 6: (bf) r2 = r10 7: (07) r2 += -229 ^^^^^^^^^^ 8: (b7) r3 = 8 9: (b7) r4 = 0 10: (85) call dev_map_lookup_elem#1543472 11: (95) exit It is due to the "void *key" (r2) passed to the helper. bpf allows uninit stack memory access for bpf prog with the right privileges. This patch uses kmsan_unpoison_memory() to mark the stack as initialized. This should address different syzbot reports on the uninit "void *key" argument during map_{lookup,delete}_elem. • https://git.kernel.org/stable/c/b30f3197a6cd080052d5d4973f9a6b479fd9fff5 https://git.kernel.org/stable/c/d812ae6e02bd6e6a9cd1fdb09519c2f33e875faf https://git.kernel.org/stable/c/3189983c26108cf0990e5c46856dc9feb9470d12 https://git.kernel.org/stable/c/e8742081db7d01f980c6161ae1e8a1dbc1e30979 •

https://notcve.org/view.php?id=CVE-2023-52887
In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new This patch enhances error handling in scenarios with RTS (Request to Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE backtraces with a new error handling method. This provides clearer error messages and allows for the early termination of problematic sessions. Previously, sessions were only released at the end of j1939_xtp_rx_rts(). Potentially this could be reproduced with something like: testj1939 -r vcan0:0x80 & while true; do # send first RTS cansend vcan0 18EC8090#1014000303002301; # send second RTS cansend vcan0 18EC8090#1014000303002301; # send abort cansend vcan0 18EC8090#ff00000000002301; done • https://git.kernel.org/stable/c/9d71dd0c70099914fcd063135da3c580865e924c https://git.kernel.org/stable/c/ed581989d7ea9df6f8646beba2341e32cd49a1f9 https://git.kernel.org/stable/c/f6c839e717901dbd6b1c1ca807b6210222eb70f6 https://git.kernel.org/stable/c/1762ca80c2b72dd1b5821c5e347713ae696276ea https://git.kernel.org/stable/c/26b18dd30e63d4fd777be429148e8e4ed66f60b2 https://git.kernel.org/stable/c/177e33b655d35d72866b50aec84307119dc5f3d4 https://git.kernel.org/stable/c/0bc0a7416ea73f79f915c9a05ac0858dff65cfed https://git.kernel.org/stable/c/d3e2904f71ea0fe7eaff1d68a2b0363c8 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-41098 – ata: libata-core: Fix null pointer dereference on error
https://notcve.org/view.php?id=CVE-2024-41098
In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: Fix null pointer dereference on error If the ata_port_alloc() call in ata_host_alloc() fails, ata_host_release() will get called. However, the code in ata_host_release() tries to free ata_port struct members unconditionally, which can lead to the following: BUG: unable to handle page fault for address: 0000000000003990 PGD 0 P4D 0 Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 10 PID: 594 Comm: (udev-worker) Not tainted 6.10.0-rc5 #44 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014 RIP: 0010:ata_host_release.cold+0x2f/0x6e [libata] Code: e4 4d 63 f4 44 89 e2 48 c7 c6 90 ad 32 c0 48 c7 c7 d0 70 33 c0 49 83 c6 0e 41 RSP: 0018:ffffc90000ebb968 EFLAGS: 00010246 RAX: 0000000000000041 RBX: ffff88810fb52e78 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff88813b3218c0 RDI: ffff88813b3218c0 RBP: ffff88810fb52e40 R08: 0000000000000000 R09: 6c65725f74736f68 R10: ffffc90000ebb738 R11: 73692033203a746e R12: 0000000000000004 R13: 0000000000000000 R14: 0000000000000011 R15: 0000000000000006 FS: 00007f6cc55b9980(0000) GS:ffff88813b300000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000003990 CR3: 00000001122a2000 CR4: 0000000000750ef0 PKRU: 55555554 Call Trace: <TASK> ? __die_body.cold+0x19/0x27 ? page_fault_oops+0x15a/0x2f0 ? exc_page_fault+0x7e/0x180 ? asm_exc_page_fault+0x26/0x30 ? • https://git.kernel.org/stable/c/633273a3ed1cf37ced90475b0f95cf81deab04f1 https://git.kernel.org/stable/c/d9c4df80b1b009de1eb77c07e3bb4d45bd212aa5 https://git.kernel.org/stable/c/56e62977eaaae3eb7122ee2cf9b720b6703114a9 https://git.kernel.org/stable/c/e83405e75d90694ee6a5d898f7f0473ac2686054 https://git.kernel.org/stable/c/221e3b1297e74fdec32d0f572f4dcb2260a0a2af https://git.kernel.org/stable/c/0f0d37c154bb108730c90a91aa31e3170e827962 https://git.kernel.org/stable/c/119c97ace2a9ffcf4dc09a23bb057d6c281aff28 https://git.kernel.org/stable/c/8a8ff7e3b736a70d7b7c8764cbcd2724d •
