kernel security update
An update for kernel is now available for openEuler-22.03-LTS.
The Linux Kernel, the operating system core itself.
Security Fix(es):
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.(CVE-2022-29901)
A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.(CVE-2022-4269)
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 size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service.(CVE-2023-1380)
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.(CVE-2023-1513)
An update for kernel is now available for openEuler-22.03-LTS.
