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 •

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-41082 – nvme-fabrics: use reserved tag for reg read/write command
https://notcve.org/view.php?id=CVE-2024-41082
In the Linux kernel, the following vulnerability has been resolved: nvme-fabrics: use reserved tag for reg read/write command In some scenarios, if too many commands are issued by nvme command in the same time by user tasks, this may exhaust all tags of admin_q. If a reset (nvme reset or IO timeout) occurs before these commands finish, reconnect routine may fail to update nvme regs due to insufficient tags, which will cause kernel hang forever. In order to workaround this issue, maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved tags. This maybe safe for nvmf: 1. For the disable ctrl path, we will not issue connect command 2. • https://git.kernel.org/stable/c/165da9c67a26f08c9b956c15d701da7690f45bcb https://git.kernel.org/stable/c/7dc3bfcb4c9cc58970fff6aaa48172cb224d85aa •
