CVE-2026-98069

In the Linux kernel, the following vulnerability has been resolved: net/rds: acquire the fastpath locks in rdsconnshutdown rdsconnshutdown quiesces the transmit and receive-refill paths by waiting for RDSINXMIT and RDSRECVREFILL to be sampled clear, and then runs the transport shutdown and...

CVE-2026-72039

In the Linux kernel, the following vulnerability has been resolved: bnx2x: fix potential memory leak in bnx2xallocmembp If the allocation of fpi.tpainfo fails, the error path will not free the struct bnx2xfastpath allocated earlier, as it is not linked to the bp structure yet. Fix that by linking...

CVE-2026-72039

The CVE-2026-72039 entry concerns the Linux kernel bug in the bnx2x driver where a potential memory leak could occur during bnx2x_alloc_mem_bp() if fp[i].tpa_info allocation fails. The fix is to link the newly allocated struct bnx2x_fastpath immediately after allocation so it is freed on error pa...

PT-2026-72228

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak exists in the bnx2x alloc mem bp function. The issue occurs when the allocation of fpi.tpa info fails, causing the error path to fail to free the previously allocated struc...

CVE-2026-64284

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 systems. This vulnerability occurs when KVM handles fastpath exits, where it may fail to execute vendor-specific cleanup operations before returning control to the virtual machine's userspace. Consequently, memory...

CVE-2026-64284

CVE-2026-64284 — Linux kernel (KVM/x86): The vulnerability involves moving the handling of fastpath userspace exits into vendor code so KVM can run vendor-specific operations before userspace gains control of the vCPU. The description notes that, for VMX (and soon SVM), KVM must flush the PML buf...
