CVE-2026-89968

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: reject unsolicited H2CData PDUs nvmettcphandleh2cdatapdu accepts an H2CData PDU after only checking that its TTAG is a valid in-range command index and that the command's data buffers are mapped. It never checks that t...

CVE-2026-89903

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Do not save/restore percpu base register in rethook trampoline The rethook trampoline saves $r21 $u0, the percpu base, into its frame at entry and restores it at exit. Inbetween rethooktrampolinehandler may schedule vi...

CVE-2026-89968

CVE-2026-89968 affects the Linux kernel's NVMe/TCP target (nvmet-tcp). The function nvmet_tcp_handle_h2c_data_pdu() accepts an H2CData PDU without verifying that the target has actually solicited the data via an R2T for that command. A remote host can exploit this by sending an H2CData PDU before...

CVE-2026-89906

CVE-2026-89906 affects the LoongArch BPF JIT in the Linux kernel. The jump offset calculation for tail calls used a stale prior-pass code stride to derive branch distances, which can produce wrong branch offsets and cause soft lockups when extra JIT passes are triggered. The fix recalculates the ...

CVE-2026-89903

CVE-2026-89903 affects the Linux kernel on the LoongArch architecture, specifically the rethook trampoline (previously the kretprobe trampoline since v6.3 ). The trampoline incorrectly saves and restores $r21 (the per-CPU base register) across its entry/exit frame. If a task migrates CPUs between...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset = -1. Therefore, t...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: jbd2: Prevent softlockup in jbd2logdocheckpoint. Both jbd2logdocheckpoint and jbd2journalshrinkcheckpointlist periodically release the jlistlock after processing a batch of buffers to avoid long hold times on the jlistlock...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/ast: Fixed soft lockup issues. There is a while-loop in astdpsetonoff, which could lead to an infinite loop. This is because the register VGACRI-Dx checked in this API is actually a scratch register controlled by an MCU named...
