fkie_cve-2023-1513

A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.

OESA-2023-1209 — kernel security update

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).(CVE-2023-23004) A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected.(CVE-2023-1249) A null pointer dereference issue was found in the unix protocol in net/unix/diag.c in Linux before 6.0. In unix_diag_get_exact, the newly allocated skb does not have sk, leading to null pointer. A local user could use this flaw to crash the system or potentially cause a denial of service.

Kernel: A denial of service issue in az6027 driver in drivers/media/usb/dev-usb/az6027.c(CVE-2023-28328) A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the si…
