CVE-2024-58015·Kernel vulnerability

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix for out-of bound access error Selfgen stats are placed in a buffer using print_array_to_buf_index() function. Array length parameter passed to the function is too big, resulting in possible out-of bound memory error. Decreasing buffer size by one fixes faulty upper bound of passed array. Discovered in coverity scan, CID 1600742 and CID 1600758

How to fix this CVE

Update your Linux kernel to version 6.13.3 or later to patch a memory bounds-checking vulnerability in the ath12k WiFi driver. This issue affects kernel versions 6.3 through 6.13.2 and could allow local privileged users to trigger kernel memory access violations. Apply the patch immediately if you are running an affected kernel version on systems with Qualcomm WiFi hardware.

sudo dnf update kernel kernel-devel

Defensia detects this vulnerability

How to check if you are affected

  1. Check your current kernel version: uname -r
  2. Verify if ath12k driver is loaded: lsmod | grep ath12k
  3. Check kernel logs for memory access errors: sudo dmesg | grep -i 'out of bounds\|ath12k.*error\|general protection'
  4. Confirm patched version is running after reboot: uname -r (should be 6.13.3 or later)

FAQ

What is CVE-2024-58015?

CVE-2024-58015 is a memory bounds-checking vulnerability in the ath12k WiFi driver within the Linux kernel. The driver incorrectly calculates buffer boundaries when writing selfgen statistics, potentially allowing out-of-bounds memory access by local users with elevated privileges.

Is CVE-2024-58015 being actively exploited?

No, according to CISA's Known Exploited Vulnerabilities (KEV) catalog, CVE-2024-58015 is not currently being actively exploited in the wild, and no public exploit code is available.

What versions of Kernel are affected by CVE-2024-58015?

Linux kernel versions 6.3 through 6.13.2 are affected. Kernel 6.13.3 and later versions contain the fix.

How do I check if my server is vulnerable to CVE-2024-58015?

Run 'uname -r' to check your kernel version; if it shows 6.3-6.13.2, you are vulnerable. Additionally, run 'lsmod | grep ath12k' to confirm the affected driver is loaded on your system.

Does Defensia detect CVE-2024-58015?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Kernel is installed on a monitored server, CVE-2024-58015 will appear in your dashboard with remediation steps.

CVE-2024-42256CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: cifs: Fix server re-repick on subrequest retry When a subrequest is marked for needing retry, netfs will call cifs_prepare_write() which will make cifs repick the server for the op before renegotiating credits; it then calls cifs_issue_write() which invokes smb2_async_writev() - which re-repicks the server. If a different server is then selected, this causes the increment of server->in_flight to happen against one record and the decrement to happen against another, leading to misaccounting. Fix this by just removing the repick code in smb2_async_writev(). As this is only called from netfslib-driven code, cifs_prepare_write() should always have been called first, and so server should never be NULL and the preparatory step is repeated in the event that we do a retry. The problem manifests as a warning looking something like: WARNING: CPU: 4 PID: 72896 at fs/smb/client/smb2ops.c:97 smb2_add_credits+0x3f0/0x9e0 [cifs] ... RIP: 0010:smb2_add_credits+0x3f0/0x9e0 [cifs] ... smb2_writev_callback+0x334/0x560 [cifs] cifs_demultiplex_thread+0x77a/0x11b0 [cifs] kthread+0x187/0x1d0 ret_from_fork+0x34/0x60 ret_from_fork_asm+0x1a/0x30 Which may be triggered by a number of different xfstests running against an Azure server in multichannel mode. generic/249 seems the most repeatable, but generic/215, generic/249 and generic/308 may also show it.
CVE-2024-36031CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: keys: Fix overwrite of key expiration on instantiation The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry.
CVE-2024-38612CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregister_pernet_subsys() with genl_unregister_family() in this error path.
CVE-2024-38623CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Use variable length array instead of fixed size Should fix smatch warning: ntfs_set_label() error: __builtin_memcpy() 'uni->name' too small (20 vs 256)
CVE-2021-47548CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off; because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function returns.
