The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6766-3 advisory.

    It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during     recursive action operations under certain conditions. A local attacker could use this to cause a denial of     service (system crash). (CVE-2024-1151)

    Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux     kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were     insufficient for Intel processors. A local attacker could potentially use this to expose sensitive     information. (CVE-2024-2201)

    Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-     bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system     crash). (CVE-2024-23849)

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-d16d94b00d advisory.

  - In btrfs_get_root_ref in fs/btrfs/disk-io.c in the Linux kernel through 6.7.1, there can be an assertion     failure and crash because a subvolume can be read out too soon after its root item is inserted upon     subvolume creation. (CVE-2024-23850)

  - copy_params in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than     INT_MAX bytes, and crash, because of a missing param_kernel->data_size check. This is related to     ctl_ioctl. (CVE-2024-23851)

  - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
    (CVE-2023-52437)

  - In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work     scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit     as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling     complete(). This seems more logical in the first place, as it's the inverse order of what the submitting     thread will do. (CVE-2024-26585)

  - In the Linux kernel, the following vulnerability has been resolved: net: tls: fix use-after-free with     partial reads and async decrypt tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so     the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when     we try to read from the partially-read skb. (CVE-2024-26582)

  - In the Linux kernel, the following vulnerability has been resolved: net: tls: handle backlogging of crypto     requests Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our requests to the crypto API,     crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in valid situations. For example,     when the cryptd queue for AESNI is full (easy to trigger with an artificially low     cryptd.cryptd_max_cpu_qlen), requests will be enqueued to the backlog but still processed. In that case,     the async callback will also be called twice: first with err == -EINPROGRESS, which it seems we can just     ignore, then with err == 0. Compared to Sabrina's original patch this version uses the new     tls_*crypt_async_wait() helpers and converts the EBUSY to EINPROGRESS to avoid having to modify all the     error handling paths. The handling is identical. (CVE-2024-26584)

  - In the Linux kernel, the following vulnerability has been resolved: tls: fix race between async notify and     socket close The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto     handler calls complete() so any code past that point risks touching already freed data. Try to avoid the     locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend     solely on the atomic ref counter for synchronization. Don't futz with reiniting the completion, either, we     are now tightly controlling when completion fires. (CVE-2024-26583)

  - In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Fix block process call     transactions According to the Intel datasheets, software must reset the block buffer index twice for block     process call transactions: once before writing the outgoing data to the buffer, and once again before     reading the incoming data from the buffer. The driver is currently missing the second reset, causing the     wrong portion of the block buffer to be read. (CVE-2024-26593)

  - In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Stop relying on userspace for     info to fault in xsave buffer Before this change, the expected size of the user space buffer was taken     from fx_sw->xstate_size. fx_sw->xstate_size can be changed from user-space, so it is possible construct a     sigreturn frame where: * fx_sw->xstate_size is smaller than the size required by valid bits in     fx_sw->xfeatures. * user-space unmaps parts of the sigrame fpu buffer so that not all of the buffer     required by xrstor is accessible. In this case, xrstor tries to restore and accesses the unmapped area     which results in a fault. But fault_in_readable succeeds because buf + fx_sw->xstate_size is within the     still mapped area, so it goes back and tries xrstor again. It will spin in this loop forever. Instead,     fault in the maximum size which can be touched by XRSTOR (taken from fpstate->user_size). [ dhansen: tweak     subject / changelog ] (CVE-2024-26603)

  - In the Linux kernel, the following vulnerability has been resolved: Revert kobject: Remove redundant     checks for whether ktype is NULL This reverts commit 1b28cb81dab7c1eedc6034206f4e8d644046ad31. It is     reported to cause problems, so revert it for now until the root cause can be found. (CVE-2024-26604)

  - In the Linux kernel, the following vulnerability has been resolved: binder: signal epoll threads of self-     work In (e)poll mode, threads often depend on I/O events to determine when data is ready for consumption.
    Within binder, a thread may initiate a command via BINDER_WRITE_READ without a read buffer and then make     use of epoll_wait() or similar to consume any responses afterwards. It is then crucial that epoll threads     are signaled via wakeup when they queue their own work. Otherwise, they risk waiting indefinitely for an     event leaving their work unhandled. What is worse, subsequent commands won't trigger a wakeup either as     the thread has pending work. (CVE-2024-26606)
