Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: arm64: io: Extract user memory type in
ioremap_prot() The only caller of ioremap_prot() outside of the generic ioremap() implementation is
generic_access_phys(), which passes a 'pgprot_t' value determined from the user mapping of the target
'pfn' being accessed by the kernel. On arm64, the 'pgprot_t' contains all of the non-address bits from the
pte, including the permission controls, and so we end up returning a new user mapping from ioremap_prot()
which faults when accessed from the kernel on systems with PAN: | Unable to handle kernel read from
unreadable memory at virtual address ffff80008ea89000 | ... | Call trace: | __memcpy_fromio+0x80/0xf8 |
generic_access_phys+0x20c/0x2b8 | __access_remote_vm+0x46c/0x5b8 | access_remote_vm+0x18/0x30 |
environ_read+0x238/0x3e8 | vfs_read+0xe4/0x2b0 | ksys_read+0xcc/0x178 | __arm64_sys_read+0x4c/0x68 Extract
only the memory type from the user 'pgprot_t' in ioremap_prot() and assert that we're being passed a user
mapping, to protect us against any changes in future that may require additional handling. To avoid
falsely flagging users of ioremap(), provide our own ioremap() macro which simply wraps __ioremap_prot().
(CVE-2026-23346)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.3 or later.
