CVE-2024-53059·Kernel vulnerability

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd() 1. The size of the response packet is not validated. 2. The response buffer is not freed. Resolve these issues by switching to iwl_mvm_send_cmd_status(), which handles both size validation and frees the buffer.

How to fix this CVE

Update your Linux kernel to version 6.11.7 or later to patch a memory handling vulnerability in the iwlwifi driver's recovery command processing. This fix ensures that Wi-Fi device recovery responses are properly validated and freed, preventing potential denial of service or privilege escalation through malformed driver responses. Systems running kernels 6.7 through 6.11.6 should prioritize this update.

sudo dnf update kernel kernel-devel && sudo reboot

How to check if you are affected

  1. Run 'uname -r' to check your current kernel version and verify if it falls within the vulnerable range (6.7 to 6.11.6)
  2. Confirm iwlwifi driver presence with 'lspci | grep -i wireless' and 'lsmod | grep iwl' to determine if the affected driver is loaded
  3. Search system logs for recovery command failures: 'grep -i 'iwl_mvm_send_recovery' /var/log/kern.log' or 'journalctl | grep iwlwifi'
  4. Verify the patch is applied by checking kernel build config: 'grep CONFIG_IWLWIFI /boot/config-$(uname -r)' and confirming kernel version is 6.11.7 or later with 'uname -r'

FAQ

What is CVE-2024-53059?

This vulnerability exists in the Linux kernel's iwlwifi driver where the recovery command handler fails to validate response packet size and improperly manages memory, leaving the response buffer unfreed. This can lead to memory exhaustion or information disclosure when a Wi-Fi device sends a malformed recovery response.

Is CVE-2024-53059 being actively exploited?

No, there is no evidence of active exploitation in the wild or public exploit code available for this vulnerability at this time.

What versions of Kernel are affected by CVE-2024-53059?

Linux kernel versions 6.7 through 6.11.6 are vulnerable. The fix is available in kernel 6.11.7 and later.

How do I check if my server is vulnerable to CVE-2024-53059?

Run 'uname -r' and compare your kernel version against the range 6.7-6.11.6. If your version falls within this range and 'lsmod | grep iwl' shows the iwlwifi driver is loaded, your system is vulnerable.

Does Defensia detect CVE-2024-53059?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Kernel is installed on a monitored server, CVE-2024-53059 will appear in your dashboard with remediation steps.

CVE-2026-43501CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows ipv6_rpl_srh_rcv() decompresses an RFC 6554 Source Routing Header, swaps the next segment into ipv6_hdr->daddr, recompresses, then pulls the old header and pushes the new one plus the IPv6 header back. The recompressed header can be larger than the received one when the swap reduces the common-prefix length the segments share with daddr (CmprI=0, CmprE>0, seg[0][0] != daddr[0] gives the maximum +8 bytes). pskb_expand_head() was gated on segments_left == 0, so on earlier segments the push consumed unchecked headroom. Once skb_push() leaves fewer than skb->mac_len bytes in front of data, skb_mac_header_rebuild()'s call to: skb_set_mac_header(skb, -skb->mac_len); will store (data - head) - mac_len into the u16 mac_header field, which wraps to ~65530, and the following memmove() writes mac_len bytes ~64KiB past skb->head. A single AF_INET6/SOCK_RAW/IPV6_HDRINCL packet over lo with a two segment type-3 SRH (CmprI=0, CmprE=15) reaches headroom 8 after one pass; KASAN reports a 14-byte OOB write in ipv6_rthdr_rcv. Fix this by expanding the head whenever the remaining room is less than the push size plus mac_len, and request that much extra so the rebuilt MAC header fits afterwards.
CVE-2026-64385CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double-free in SMB2_ioctl() replay A response-bearing attempt can return a replayable error and free its response buffer. If SMB2_ioctl_init() fails before the next send, cleanup retains the previous buffer type and frees that response again. Reset response bookkeeping before each attempt to prevent the stale free.
CVE-2026-64391CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for ADS I/O Alternate data streams are stored as xattrs. Unlike regular file I/O, their read and write paths therefore call VFS xattr helpers which recheck inode permissions and LSM policy using the current task credentials. Run ADS I/O with the credentials captured when the SMB handle was opened.
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-2026-53176CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN In drivers/infiniband/ulp/isert/ib_isert.c, isert_login_recv_done() computes the login request payload length as wc->byte_len minus ISER_HEADERS_LEN with no lower bound, and login_req_len is a signed int. A remote iSER initiator can post a login Send work request carrying fewer than ISER_HEADERS_LEN (76) bytes, so the subtraction underflows and login_req_len becomes negative. isert_rx_login_req() then reads that negative length back into a signed int, takes size = min(rx_buflen, MAX_KEY_VALUE_PAIRS), and because the min() is signed it keeps the negative value; the value is then passed as the memcpy() length and sign-extended to a multi-gigabyte size_t. The copy into the 8192-byte login->req_buf runs far out of bounds and faults, crashing the target node. The login phase precedes iSCSI authentication, so no credentials are required to reach this path. Reject any login PDU shorter than ISER_HEADERS_LEN before the subtraction, mirroring the existing early return on a failed work completion, so login_req_len can never go negative. The upper bound was already safe: a posted login buffer cannot deliver more than ISER_RX_PAYLOAD_SIZE, so the difference stays at or below MAX_KEY_VALUE_PAIRS and the existing min() clamps it; only the missing lower bound needs to be added.
