A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling btrfs_ioctl_defrag(). • https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://patchwork.kernel.org/project/linux-btrfs/patch/20220721074829.2905233-1-r33s3n6%40gmail.com https://security.netapp.com/advisory/ntap-20230703-0007 https://www.debian.org/security/2023/dsa-5480 • CWE-416: Use After Free •

A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation. Se encontró una falla en el código de registro de búfer fijo para io_uring (io_sqe_buffer_register en io_uring/rsrc.c) en el kernel de Linux que permite el acceso fuera de los límites a la memoria física más allá del final del búfer. Esta falla permite la escalada completa de privilegios locales. • https://github.com/ysanatomic/io_uring_LPE-CVE-2023-2598 https://github.com/cainiao159357/CVE-2023-2598 http://www.openwall.com/lists/oss-security/2024/04/24/3 https://security.netapp.com/advisory/ntap-20230703-0006 https://www.openwall.com/lists/oss-security/2023/05/08/3 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-3006 – RHEL: Add Spectre-BHB mitigation for AmpereOne
https://notcve.org/view.php?id=CVE-2023-3006
A known cache speculation vulnerability, known as Branch History Injection (BHI) or Spectre-BHB, becomes actual again for the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted branches within the victim's hardware context. Once that occurs, speculation caused by the mispredicted branches can cause cache allocation. This issue leads to obtaining information that should not be accessible. A known cache speculation vulnerability, the Branch History Injection (BHI) or Spectre-BHB, was found in new hw (that are cores Cortex: A57, A72, A76, A77, A78, A78AE, A78C, A710, X1, X2; Neoverse: N1, N2, V1; Ampere1). • https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=0e5d5ae837c8 https://access.redhat.com/security/cve/CVE-2023-3006 https://bugzilla.redhat.com/show_bug.cgi?id=2141026 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer CWE-226: Sensitive Information in Resource Not Removed Before Reuse •

https://notcve.org/view.php?id=CVE-2023-34256
An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access. Se ha descubierto un problema en el kernel de Linux en las versiones anteriores a 6.3.3. Hay una lectura fuera de límites en crc16 en "lib/crc16.c" cuando se llama dese "fs/ext4/super.c" porque "ext4_group_desc_csum" no comprueba correctamente un desplazamiento. • https://bugzilla.suse.com/show_bug.cgi?id=1211895 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4f04351888a83e595571de672e0a4a8b74f4fb31 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://syzkaller.appspot.com/bug?extid=8785e41224a3afd04321 • CWE-125: Out-of-bounds Read •
