🛡️ CVE-2024-47715 on Ubuntu — linux
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: fix oops on non-dbdc mt7986 mt7915_band_config() sets band_idx = 1 on the main phy for mt7986 with MT7975_ONE_ADIE or MT7976_ONE_ADIE. Commit 0335c034e726 ("wifi: mt76: fix race condition related to checking tx queue fill status") introduced a dereference of the phys array indirectly indexed by band_idx via wcid->phy_idx in mt76_wcid_cleanup(). This caused the following Oops on affected mt7986 devices: Unable to handle kernel read from unreadable memory at virtual address 0000000000000024 Mem abort info: ESR = 0x0000000096000005 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x05: level 1 translation fault Data abort info: ISV = 0, ISS = 0x00000005 CM = 0, WnR = 0 user pgtable: 4k pages, 39-bit VAs, pgdp=0000000042545000 [0000000000000024] pgd=0000000000000000, p4d=0000000000000000, pud=0000000000000000 Internal error: Oops: 0000000096000005 [#1] SMP Modules linked in: ... mt7915e mt76_connac_lib mt76 mac80211 cfg80211 ...

Distribution advisory
This page covers CVE-2024-47715 as tracked by Ubuntu, for the package linux. The fix is available in version 6.8.0-54.56; earlier versions remain affected.
How this vulnerability can be exploited
This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
CVSS metrics in full
The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Attack vector: Local — a local account, shell or session on the host is needed.
- Attack complexity: Low — the attack works reliably, with no preparation.
- Privileges required: Low — an ordinary user account is enough.
- User interaction: None — nobody has to be tricked into anything.
- Scope: Unchanged — the damage stays inside the vulnerable component.
- Confidentiality impact: None.
- Integrity impact: None.
- Availability impact: High — total loss, or loss the attacker controls.
