CVE-2024-26958
CVE-2024-26958 is a Linux kernel vulnerability in the NFS direct write path that could cause use-after-free (refcount underflow) when completing nfs_direct_request twice in a row. A patch fixes the double-completion scenario; the CVSS 3.1 base score is 7.8 (High) with Local attack and High impact...
CVE-2024-26958
In the Linux kernel, the following vulnerability has been resolved: nfs: fix UAF in direct writes In production we have been hitting the following warning consistently ------------ cut here ------------ refcountt: underflow; use-after-free. WARNING: CPU: 17 PID: 1800359 at lib/refcount.c:28...
kernel: net/mlx5e: xsk: Fix crash on regular rq reactivation
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: xsk: Fix crash on regular rq reactivation When the regular rq is reactivated after the XSK socket is closed it could be reading stale cqes which eventually corrupts the rq. This leads to no more traffic being received ...

kernel: Linux kernel: Privilege escalation via out-of-bounds write in RDMA/siw
A flaw was identified in the Linux kernel RDMA siw implementation where an undefined opcode value could be used during immediate work request flushing while in an error state. The send queue element opcode was not correctly set, which could lead to an out-of-bounds access when mapping between the...
kernel: RDMA/irdma: Fix data race on CQP request done
A race condition was identified in the RDMA/irdma subsystem of the Linux kernel affecting how completion queue pair CQP requests are processed. The cqprequest-requestdone memory location is accessed without appropriate synchronization in the irdmahandlecqpop function while it is concurrently...
kernel: RDMA/efa: Fix wrong resources deallocation order
In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If t...
kernel: RDMA/irdma: Fix data race on CQP completion stats
The Linux kernel contains a race condition vulnerability in its RDMA/irdma subsystem, where completion queue pair CQP completion statistics are read concurrently without adequate synchronization while being updated on another CPU. Under certain workloads, a lack of atomic operations and improper...
kernel: blk-mq: release crypto keyslot before reporting I/O complete
A flaw was identified in the block multi-queue blk-mq subsystem of the Linux kernel where the crypto keyslot associated with a block I/O request could be released after upper layers have been notified that the I/O operation completed. Under certain conditions, this could lead to a use-after-free ...
kernel: io_uring/net: don't overflow multishot recv
A flaw was found in the Linux kernel's iouring subsystem. When using multishot receive operations, completion queue entries CQEs can overflow without proper limits. This can lead to excessive memory consumption, performance degradation, and in worst cases, an out-of-memory OOM condition for the...
