CVE-2026-89719

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> zram: fix out-of-bounds access in read_block_state()<br /> <br /> read_block_state() calculates nr_pages before taking dev_lock. If the<br /> device is reset and reinitialized with a smaller disksize before lock<br /> acquisition, nr_pages still describes the old table. The subsequent loop<br /> can then call slot_lock() past the end of the newly allocated table.<br /> <br /> Read disksize after acquiring dev_lock and checking that the device is<br /> initialized. The read lock then keeps the table and its bound stable for<br /> the duration of the scan.
