CVE-2022-49163·Kernel vulnerability

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: fix a bug of accessing array out of bounds When error occurs in parsing jpeg, the slot isn't acquired yet, it may be the default value MXC_MAX_SLOTS. If the driver access the slot using the incorrect slot number, it will access array out of bounds. The result is the driver will change num_domains, which follows slot_data in struct mxc_jpeg_dev. Then the driver won't detach the pm domain at rmmod, which will lead to kernel panic when trying to insmod again.

How to fix this CVE

Update your Linux kernel to version 5.17.2 or later to patch the array bounds vulnerability in the imx-jpeg media driver. This vulnerability can cause memory corruption and kernel panic during module reloading if JPEG parsing errors occur. Apply the kernel update and reboot your system to resolve the issue.

sudo dnf update kernel

Defensia detects this vulnerability

How to check if you are affected

  1. Step 1: Check the installed kernel version using 'uname -r' and verify if it falls between 5.17 and 5.17.1
  2. Step 2: Verify if the imx-jpeg driver is loaded by running 'lsmod | grep imx_jpeg' (if present, the vulnerable component is active)
  3. Step 3: Search kernel logs for JPEG parsing errors using 'dmesg | grep -i jpeg' or 'journalctl -xe | grep -i jpeg'
  4. Step 4: After updating, run 'uname -r' again to confirm kernel version is 5.17.2 or higher, then verify imx-jpeg loads without errors after module reload

FAQ

What is CVE-2022-49163?

CVE-2022-49163 is an array out-of-bounds vulnerability in the Linux kernel's imx-jpeg media driver that occurs when JPEG parsing fails before acquiring a valid slot index, leading to memory corruption and potential kernel panic on module reload.

Is CVE-2022-49163 being actively exploited?

No, CVE-2022-49163 is not listed as actively exploited in CISA's Known Exploited Vulnerabilities catalog, and no public exploits are available.

What versions of Kernel are affected by CVE-2022-49163?

Linux kernel versions 5.17 through 5.17.1 are affected; the vulnerability was fixed in kernel 5.17.2.

How do I check if my server is vulnerable to CVE-2022-49163?

Run 'uname -r' to check your kernel version; if it shows 5.17.0 or 5.17.1, you are vulnerable. Additionally, check if the imx-jpeg driver is active with 'lsmod | grep imx_jpeg'.

Does Defensia detect CVE-2022-49163?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If the Linux kernel is installed on a monitored server, CVE-2022-49163 will appear in your dashboard with remediation steps.

CVE-2026-100075CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Fix srpt_alloc_rw_ctxs() unwind counters When srpt_alloc_rw_ctxs() fails partway through a multi-buffer indirect descriptor, the unwind path destroys RDMA contexts but leaves stale n_rw_ctx and n_rdma values (and a dangling rw_ctxs pointer). Later sq_wr_avail accounting in srpt_queue_response() or srpt_write_pending() can then subtract the wrong number of send queue credits. Reset the counters and clear rw_ctxs after freeing the heap allocation before returning an error.

When the encrypt_name resolves to an async AEAD instance the request returns -EINPROGRESS, the buffer is freed while the backend's worker still holds a pointer, and the worker dereferences the freed slab on completion.

Reachable via net/rxrpc/rxgk.c, fs/afs/cm_security.c and net/ceph/crypto.c on systems with an async AEAD provider bound to the krb5 enctype name.
CVE-2026-64066CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: netfs: Fix netfs_read_to_pagecache() to pause on subreq failure Fix netfs_read_to_pagecache() so that it pauses the generation of new subrequests if an already-issued subrequest fails.
CVE-2026-64383CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double-free in SMB2_flush() replay SMB2_flush() keeps its response buffer bookkeeping across replay attempts. If a replayable flush response is received and the retry then fails before cifs_send_recv() stores a replacement response, flush_exit will free the stale response pointer a second time. Reinitialize resp_buftype and rsp_iov at the top of the replay loop so cleanup only acts on response state produced by the current attempt. This fixes a double-free without changing replay handling for successful requests.
CVE-2026-64067CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: netfs: Fix missing barriers when accessing stream->subrequests locklessly The list of subrequests attached to stream->subrequests is accessed without locks by netfs_collect_read_results() and netfs_collect_write_results(), and then they access subreq->flags without taking a barrier after getting the subreq pointer from the list. Relatedly, the functions that build the list don't use any sort of write barrier when constructing the list to make sure that the NETFS_SREQ_IN_PROGRESS flag is perceived to be set first if no lock is taken. Fix this by: (1) Add a new list_add_tail_release() function that uses a release barrier to set the pointer to the new member of the list. (2) Add a new list_first_entry_or_null_acquire() function that uses an acquire barrier to read the pointer to the first member in a list (or return NULL). (3) Use list_add_tail_release() when adding a subreq to ->subrequests. (4) Use list_first_entry_or_null_acquire() when initially accessing the front of the list (when an item is removed, the pointer to the new front iterm is obtained under the same lock).
