The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

powerpc/xive/spapr: correct bitmap allocation size

This happens because the allocation uses the wrong unit (bits) when it should pass (BITS_TO_LONGS(count) * sizeof(long)) or equivalent. With small numbers of bits, the allocated object can be smaller than sizeof(long), which results in invalid accesses.

Use bitmap_zalloc() to allocate and initialize the irq bitmap, paired with bitmap_free() for consistency.(CVE-2022-49623)

In the Linux kernel, the following vulnerability has been resolved:

wifi: at76c50x: fix use after free access in at76_disconnect

The memory pointed to by priv is freed at the end of at76_delete_device function (using ieee80211_free_hw). But the code then accesses the udev field of the freed object to put the USB device. This may also lead to a memory leak of the usb device. Fix this by using udev from interface.(CVE-2025-37796)

In the Linux kernel, the following vulnerability has been resolved:

codel: remove sch->q.qlen check before qdisc_tree_reduce_backlog()

After making all ->qlen_notify() callbacks idempotent, now it is safe to remove the check of qlen!=0 from both fq_codel_dequeue() and codel_qdisc_dequeue().(CVE-2025-37798)

In the Linux kernel, the following vulnerability has been resolved:

net_sched: qfq: Fix double list add in class with netem as child qdisc
