USN-6699-1: Linux kernel vulnerabilities

Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service guest crash. CVE-2023-30456 It was discovered that the...

CVE-2023-52493

A flaw was found in the Linux Kernel. Read and write locks for the channel are taken in succession by dropping the read lock from parsexferevent, such that a callback given to client can potentially queue buffers and acquire the write lock in that process. This can result in multiple locks and a...

SUSE CVE-2021-46973

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: Avoid potential use after free in MHI send It is possible that the MHI ulcallback will be invoked immediately following the queueing of the skb for transmission, leading to the callback decrementing the refcount of the...

USN-6479-1 linux-oem-6.5 vulnerabilities

Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service system crash. CVE-2023-42756 Alex Birnberg discovered that the netfilter subsystem in the Linux...

kernel: net/sched: sch_fq: fix integer overflow of "credit"

An integer overflow flaw was found in the Linux kernel network fair-queueing scheduler in the way the initial per-flow credit is set. If a configuration provides an excessively large initial quantum, the credit value can overflow to a negative number, leading to excessive scheduling and soft...

kernel: use-after-free due to race condition in qdisc_graft()

A use-after-free flaw was found in qdiscgraft in net/sched/schapi.c in the Linux Kernel due to a race problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 "net: sched: fix race condition in qdiscgraft" not applied yet, then kernel could be affected...
