CVE-2023-3268 – kernel: out-of-bounds access in relay_file_read
https://notcve.org/view.php?id=CVE-2023-3268
An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel internal information.

CVE-2023-3161 – kernel: fbcon: shift-out-of-bounds in fbcon_set_font()
https://notcve.org/view.php?id=CVE-2023-3161
A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds occurs leading to undefined behavior and possible denial of service.

CVE-2023-3141 – kernel: Use after free bug in r592_remove
https://notcve.org/view.php?id=CVE-2023-3141
A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the Linux Kernel.

CVE-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 •
