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: udf: validate sparing table length as
an entry count, not a byte count udf_load_sparable_map() accepts a sparing table when sizeof(*st) +
le16_to_cpu(st->reallocationTableLen) > sb->s_blocksize is false, i.e. it treats reallocationTableLen as a
number of BYTES that must fit in the block. But the table is walked as an array of 8-byte sparingEntry
elements: for (i = 0; i < le16_to_cpu(st->reallocationTableLen); i++) { struct sparingEntry *entry =
&st->mapEntry[i]; ... entry->origLocation ... } in udf_get_pblock_spar15() and udf_relocate_blocks(). A
reallocationTableLen of N therefore passes the check whenever sizeof(*st) + N <= blocksize, yet the
consumers index sizeof(*st) + N * sizeof(struct sparingEntry) bytes -- up to ~8x the block. On a crafted
UDF image this is an out-of-bounds read in udf_get_pblock_spar15(); udf_relocate_blocks() additionally
feeds the same length to udf_update_tag(), whose crc_itu_t() reads far past the block, and its memmove()
through st->mapEntry[] is an out-of-bounds write. Validate reallocationTableLen as the entry count it is,
with struct_size(). (CVE-2026-64322)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.37 or later.
