UBUNTU-CVE-2026-23379

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: fix divide by zero in the offload path Offloading ETS requires computing each class' WRR weight: this is done by averaging over the sums of quanta as 'qsum' and 'qpsum'. Using unsigned int, the same integer size a...

UBUNTU-CVE-2026-23298

In the Linux kernel, the following vulnerability has been resolved: can: ucan: Fix infinite loop from zero-length messages If a broken ucan device gets a message with the message length field set to 0, then the driver will loop for forever in ucanreadbulkcallback, hanging the system. If the lengt...

UBUNTU-CVE-2026-23373

In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: Don't default to -EOPNOTSUPP in rsimac80211config This triggers a WARNON in ieee80211hwconfinit and isn't the expected behavior from the driver - other drivers default to 0 too...

UBUNTU-CVE-2026-23377

In the Linux kernel, the following vulnerability has been resolved: ice: change XDP RxQ fragsize from DMA write length to xdp.framesz The only user of fragsize field in XDP RxQ info is bpfxdpfragsincreasetail. It clearly expects whole buff size instead of DMA write size. Different assumptions in...

Sen. Wyden Warns of Another Section 702 Abuse

Sen. Ron Wyden is warning us of an abuse of Section 702: Wyden took to the Senate floor to deliver a lengthy speech, ostensibly about the since approved with support of many Democrats nomination of Joshua Rudd to lead the NSA. Wyden was protesting that nomination, but in the context of Rudd being...

CVE-2026-23379

CVE-2026-23379 affects the Linux kernel net/sched ETS offload path. The root cause was an overflow in WRR weight computation (q_sum, q_psum) due to using 32-bit unsigned integers, which could lead to division by zero. The documented fix is to switch q_sum and q_psum to 64-bit integers, preventing...

CVE-2026-23356

The CVE-2026-23356 issue affects the Linux kernel DRBD subsystem. A logic bug in drbd_al_begin_io_nonblock() could mis-handle a reference-counted extent when lc_get_cumulative() and lc_try_lock() timing collided, risking a crash or incorrect assumption that an activity log extent is active during...
