    CVE-2011-10027 – AOL Desktop Buffer Overflow Vulnerability

    August 20, 2025

    CVE ID : CVE-2011-10027

    Published : Aug. 20, 2025, 4:15 p.m. | 8 hours, 35 minutes ago

    Description : AOL Desktop 9.6 contains a buffer overflow vulnerability in its Toolrich.rct component when parsing .rtx files. By embedding an overly long string in a hyperlink tag, an attacker can trigger a stack-based buffer overflow due to the use of unsafe strcpy operations. This allows remote attackers to execute arbitrary code when a victim opens a malicious .rtx file. AOL Desktop is end-of-life and no longer supported. Users are encouraged to migrate to AOL Desktop Gold or alternative platforms.

    Severity: 8.4 | HIGH

    CVE ID : CVE-2025-37827

    Published : May 8, 2025, 7:15 a.m. | 58 minutes ago

    Description : In the Linux kernel, the following vulnerability has been resolved:

    btrfs: zoned: return EIO on RAID1 block group write pointer mismatch

    There was a bug report about a NULL pointer dereference in
    __btrfs_add_free_space_zoned() that ultimately happens because a
    conversion from the default metadata profile DUP to a RAID1 profile on two
    disks.

    The stack trace has the following signature:

    BTRFS error (device sdc): zoned: write pointer offset mismatch of zones in raid1 profile
    BUG: kernel NULL pointer dereference, address: 0000000000000058

    BTRFS error (device sdc): zoned: write pointer offset mismatch of zones in raid1 profile

    When a RAID1 block-group is created and a write pointer mismatch between
    the disks in the RAID set is detected, btrfs sets the alloc_offset to the
    length of the block group marking it as full. Afterwards the code expects
    that a balance operation will evacuate the data in this block-group and
    repair the problems.

    But before this is possible, the new space of this block-group will be
    accounted in the free space cache. But in __btrfs_
