In the Linux kernel, the following vulnerability has been resolved: macvlan: fix error recovery in macvlan_common_newlink() valis provided a nice repro to crash the kernel: ip link add p1 type veth peer p2 ip link set address 00:00:00:00:00:20 dev p1 ip link set up dev p1 ip link set up dev p2 ip link add mv0 link p2 type macvlan mode source ip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20 ping -c1 -I p1 1.2.3.4 He also gave a very detailed analysis: <quote valis> The issue is triggered when a new macvlan link is created with MACVLAN_MODE_SOURCE mode and MACVLAN_MACADDR_ADD (or MACVLAN_MACADDR_SET) parameter, lower device already has a macvlan port and register_netdevice() called from macvlan_common_newlink() fails (e.g. because of the invalid link name). In this case macvlan_hash_add_source is called from macvlan_change_sources() / macvlan_common_newlink(): This adds a reference to vlan to the port's vlan_source_hash using macvlan_source_entry. vlan is a pointer to the priv data of the link that is being created. When register_netdevice() fails, the error is returned from macvlan_newlink() to rtnl_newlink_create(): if (ops->newlink) err = ops->newlink(dev, &params, extack); else err = register_netdevice(dev); if (err < 0) { free_netdev(dev); goto out; } and free_netdev() is called, causing a kvfree() on the struct net_device that is still referenced in the source entry attached to the lower device's macvlan port. Now all packets sent on the macvlan port with a matching source mac address will trigger a use-after-free in macvlan_forward_source(). </quote valis> With all that, my fix is to make sure we call macvlan_flush_sources() regardless of @create value whenever "goto destroy_macvlan_port;" path is taken. Many thanks to valis for following up on this issue.

There was a device discovery/fabric scan in progress. A module unload was issued which     set the UNLOADING flag. As part of the discovery, after receiving an interrupt a work queue was scheduled     (which involved a work to be queued). Since the UNLOADING flag is set, the work item was not allocated and     the mapped memory had to be freed. The free occurred in interrupt context leading to system crash. Delay     the driver unload until the fabric scan is complete to avoid the crash. (CVE-2025-71235)

    In the Linux kernel, the following vulnerability has been resolved: nilfs2: Fix potential block overflow     that cause system hang When a user executes the FITRIM command, an underflow can occur when calculating     nblocks if end_block is too small. Since nblocks is of type sector_t, which is u64, a negative nblocks     value will become a very large positive integer. This ultimately leads to the block layer function
    __blkdev_issue_discard() taking an excessively long time to process the bio chain, and the ns_segctor_sem     lock remains held for a long period. This prevents other tasks from acquiring the ns_segctor_sem lock,     resulting in the hang reported by syzbot in [1]. If the ending block is too small, typically if it is     smaller than 4KiB range, depending on the usage of the segment 0, it may be possible to attempt a discard     request beyond the device size causing the hang. Exiting successfully and assign the discarded size (0 in     this case) to range->len. Although the start and len values in the user input range are too small, a     conservative strategy is adopted here to safely ignore them, which is equivalent to a no-op; it will not     perform any trimming and will not throw an error.

    In the Linux kernel, the following vulnerability has been resolved: romfs: check sb_set_blocksize() return     value romfs_fill_super() ignores the return value of sb_set_blocksize(), which can fail if the requested     block size is incompatible with the block device's configuration. This can be triggered by setting a loop     device's block size larger than PAGE_SIZE using ioctl(LOOP_SET_BLOCK_SIZE, 32768), then mounting a romfs     filesystem on that device. When sb_set_blocksize(sb, ROMBSIZE) is called with ROMBSIZE=4096 but the device     has logical_block_size=32768, bdev_validate_blocksize() fails because the requested size is smaller than     the device's logical block size. sb_set_blocksize() returns 0 (failure), but romfs ignores this and     continues mounting. The superblock's block size remains at the device's logical block size (32768). Later,     when sb_bread() attempts I/O with this oversized block size, it triggers a kernel BUG in folio_set_bh():
    kernel BUG at fs/buffer.c:1582! BUG_ON(size > PAGE_SIZE); Fix by checking the return value of     sb_set_blocksize() and failing the mount with -EINVAL if it returns 0. (CVE-2026-23238)

    In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: fix use-after-free in     driver_override_show() The driver_override_show() function reads the driver_override string without     holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and     frees the string while holding the device_lock. This can result in a concurrent use-after-free if the     string is freed by the store function while being read by the show function. Fix this by holding the     device_lock around the read operation. (CVE-2026-23221)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    The Qualys Threat Research Unit (TRU) discovered several vulnerabilities     in Apparmor. Details can be found in the Qualys advisory at     https://www.qualys.com/2026/03/10/crack-armor.txt

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.164-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    macvlan: fix error recovery in macvlan_common_newlink() (CVE-2026-23209)

    In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: fix use-after-free in     driver_override_show() The driver_override_show() function reads the driver_override string without     holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and     frees the string while holding the device_lock. This can result in a concurrent use-after-free if the     string is freed by the store function while being read by the show function. Fix this by holding the     device_lock around the read operation. (CVE-2026-23221)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.73-1.

    We recommend that you upgrade your linux packages.

  - macvlan: fix error recovery in macvlan_common_newlink() valis provided a nice repro to crash the kernel:
    ip link add p1 type veth peer p2 ip link set address 00:00:00:00:00:20 dev p1 ip link set up dev p1 ip     link set up dev p2 ip link add mv0 link p2 type macvlan mode source ip link add invalid% link p2 type     macvlan mode source macaddr add 00:00:00:00:00:20 ping -c1 -I p1 1.2.3.4 He also gave a very detailed     analysis: <quote valis> The issue is triggered when a new macvlan link is created with MACVLAN_MODE_SOURCE     mode and MACVLAN_MACADDR_ADD (or MACVLAN_MACADDR_SET) parameter, lower device already has a macvlan port     and register_netdevice() called from macvlan_common_newlink() fails (e.g. because of the invalid link     name). In this case macvlan_hash_add_source is called from macvlan_change_sources() /     macvlan_common_newlink(): This adds a reference to vlan to the port's vlan_source_hash using     macvlan_source_entry. vlan is a pointer to the priv data of the link that is being created. When     register_netdevice() fails, the error is returned from macvlan_newlink() to rtnl_newlink_create(): if     (ops->newlink) err = ops->newlink(dev, ms, extack); else err = register_netdevice(dev); if (err < 0)     { free_netdev(dev); goto out; } and free_netdev() is called, causing a kvfree() on the struct net_device     that is still referenced in the source entry attached to the lower device's macvlan port. Now all packets     sent on the macvlan port with a matching source mac address will trigger a use-after-free in     macvlan_forward_source(). </quote valis> With all that, my fix is to make sure we call     macvlan_flush_sources() regardless of @create value whenever goto destroy_macvlan_port; path is taken.
    Many thanks to valis for following up on this issue. (CVE-2026-23209)

Note that Nessus relies on the presence of the package as reported by the vendor.
