An update of the linux package has been released.

The remote Ubuntu 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6250-1 advisory.

    Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux     kernel did not properly perform permission checks in certain situations. A local attacker could possibly     use this to gain elevated privileges. (CVE-2023-2640)

    It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory     in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause     a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090)

    Mingi Cho discovered that the netfilter subsystem in the Linux kernel did not properly validate the status     of a nft chain while performing a lookup by id, leading to a use-after-free vulnerability.

    It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error     conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-3390)

    Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain     pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35001)

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5448 advisory.

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system. (CVE-2023-2156)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in     the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend     upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

  - An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process. (CVE-2023-31084)

  - A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
    (CVE-2023-3212)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

  - distros-[DirtyVMA] Privilege escalation via non-RCU-protected VMA traversal [fedora-all] (CVE-2023-3269)
