The Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202664808 advisory. kernel: can: bcm: add locking for bcmop runtime updates CVE-2025-38004 kernel: iouring/poll: fix signed comparison in iopollgetownership CVE-2026-52933...
ROS-20260930-73-0001
The vulnerability of the iopollremove function in the iouring/poll.c module of the Linux kernel’s asynchronous I/O interface involves a lack of checking for the return value. Exploiting this vulnerability could allow an attacker to cause a service failure...
CVE-2026-97619
A flaw was found in the Linux kernel's iouring subsystem. Improperly deferring write completion accounting to background task work can create a circular locking dependency when a filesystem freeze operation is performed. A local user could exploit this flaw by issuing asynchronous write operation...
CVE-2026-97618
A flaw was found in the Linux kernel's iouring subsystem. This vulnerability allows a local user to cause a denial of service DoS or buffer corruption. When handling network receive operations configured with the packet truncation flag MSGTRUNC, the kernel calculates buffer consumption based on t...
Harvest Season for SLUB: From Io_uring Vulnerability to Novel Sheaf-Based Exploitation Techniques
The Linux kernel's push for higher I/O performance and more efficient memory management has introduced new mechanisms that, while improving performance, also open new attack surfaces. This research examines two of them together: the iouring subsystem and the sheaf/barn caching mechanism added to...
ROS-20260929-73-0146
The vulnerability of the ioopenatprep function in the iouring/openclose.c module, a component of the Linux kernel’s asynchronous input/output interface, relates to the failure to release resources after their useful period has ended. Exploiting this vulnerability could allow an attacker to cause...
CVE-2026-97619
In the Linux kernel, the following vulnerability has been resolved: iouring/rw: end write accounting from -kicomplete Commit b000145e9907 moved both the fsnotify calls and the write accounting out of the kiocb completion handler and into the ioreqrwcomplete taskwork. However, only the fsnotify pa...

CVE-2026-97618 io_uring/net: don't overconsume buffers when using MSG_TRUNC
In the Linux kernel, the following vulnerability has been resolved: iouring/net: don't overconsume buffers when using MSGTRUNC When a recv/recvmsg is issued with MSGTRUNC and the incoming packet is larger than the provided buffer, the net layer returns the full length of the packet rather than th...
CVE-2026-97618
The Linux kernel contains a vulnerability in the io_uring/net subsystem where a recv/recvmsg operation using MSG_TRUNC causes the system to overconsume buffers. Specifically, if an incoming packet exceeds the provided buffer size, the net layer returns the full packet length instead of the number...
CVE-2026-97619
The Linux kernel contains a vulnerability in the io_uring subsystem regarding write accounting. Specifically, moving write accounting out of the kiocb completion handler and into io_req_rw_complete() task work creates a risk where dropping SB_FREEZE_WRITE protection depends on a task that may be ...
