CVE-2025-37922
MediumSummary
W jądrze Linuxa rozwiązano podatność dotyczącą wyrównania adresu początkowego sekcji vmemmap do rozmiaru PAGE_SIZE. Altmap vmemmap jest regionem dostarczanym przez urządzenie, który służy do zapewnienia pamięci dla struktur stron.
Risk Assessment
Brak odpowiedniego wyrównania adresu może prowadzić do problemów z zarządzaniem pamięcią w różnych przestrzeniach nazw, co może wpłynąć na stabilność systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe zarządzanie pamięcią.

Before versions 1.7.4 and 2.0.0-beta.4, the Discord OAuth provider in FriendsOfFlarum does not check the 'verified' field for an OAuth email before passing it to Flarum core as trusted. This allows an unauthenticated attacker who knows a victim's email address to configure a Discord account with that unverified address and sign in as the victim without a password.

In Piwigo up to version 17.0.0beta1, when rating is enabled, an unauthenticated guest can call pwg.images.filteredSearch.create with a crafted ratings[] value and open the returned search URL. The value is not validated and is used as the upper bound in an SQL query, allowing extraction of database information or time delays.

In Piwigo before version 16.4.0, admin/themes_standard_pages.php validates uploaded logo content by MIME type but reuses the attacker-controlled extension in the filename. An authenticated administrator can upload a file with a server-executable extension, leading to code execution when placed in the logo directory.

In the Linux kernel, in the RDMA/srpt driver, the function srpt_alloc_rw_ctxs() on partial failure does not reset the n_rw_ctx and n_rdma counters and does not clear the rw_ctxs pointer, leading to incorrect send queue credit accounting. The fix resets the counters and clears the pointer before returning an error.
