In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Fix cwnd update ordering After a reconnect, the reply handler is opening the cwnd (and thus enabling more RPC Calls to be sent) /before/ rpcrdma_post_recvs() can post enough Receive WRs to receive their replies. This causes an RNR and the new connection is lost immediately. The race is most clearly exposed when KASAN and disconnect injection are enabled. This slows down rpcrdma_rep_create() enough to allow the send side to post a bunch of RPC Calls before the Receive completion handler can invoke ib_post_recv().

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7413-1 advisory.

    Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error     conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this     vulnerability to cause a denial of service. (CVE-2022-38096)

    Ye Zhang and Nicolas Wu discovered that the io_uring subsystem in the Linux kernel did not properly handle     locking for rings with IOPOLL, leading to a double-free vulnerability. A local attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-21400)

    Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2024-23848)

    Attila Szsz discovered that the HFS+ file system implementation in the Linux Kernel contained a heap     overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted,     could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2025-0927)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7173-2 advisory.

    Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error     conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this     vulnerability to cause a denial of service. (CVE-2022-38096)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:
